Circles and circular segments
Students work with central and inscribed angles, tangent lines, sectors, circular segments, and overlap areas. These topics reward careful diagram reading and exact area calculations.
Explore circle problem strategies
Competition geometry, made structured
Live, small-group geometry instruction turns diagrams into ratios, equations, proofs, and repeatable problem-solving strategies.
AMC 8 geometry tutoring is targeted instruction for students who need to recognize and solve competition-style problems involving angles, triangles, circles, quadrilaterals, area, similarity, coordinates, and spatial reasoning. ACE Academy’s Geometry course combines school-aligned foundations with AoPS-based competition thinking, so students practice explaining why a solution works rather than only memorizing a formula. The course is designed for students currently taking or who have completed Algebra I, as well as students moving toward Honors mathematics or AMC 8 preparation.
For a broader competition pathway, families can review AMC 8 preparation and compare it with focused geometry support.
The course moves from visual intuition to logical reasoning, then connects plane geometry to algebraic and spatial models.
Students work with central and inscribed angles, tangent lines, sectors, circular segments, and overlap areas. These topics reward careful diagram reading and exact area calculations.
Explore circle problem strategiesLunes and other composite shapes require students to subtract and add familiar regions. The focus is on selecting the right decomposition before calculating.
Practice composite-area reasoningCongruence, similarity, right triangles, rhombi, kites, trapezoids, and parallelograms form the working vocabulary for many AMC-style diagrams.
Build triangle and quadrilateral fluencyA representative use case
Suppose two circles pass through each other’s centers and the distance between their centers is 6. A student can split the common lens into two circular segments, calculate the sector area as 12π, subtract the associated isosceles-triangle area of 9√3, and double the result. The common area is therefore 24π − 18√3. This is the kind of translation from picture to structure that AMC 8 geometry tutoring is designed to make more familiar.
See worked geometry examplesThe learning experience is built around a deliberate progression rather than disconnected worksheets.
Build a progression from angles and triangle relationships to similarity, circles, spatial geometry, coordinates, and trigonometry.

The course is intended for students currently taking or who have completed Algebra I, or students coming from the listed Pre-Algebra or equivalent pathways. It is especially relevant for learners who want stronger geometric reasoning, proof construction, similarity, circles, or multi-step problem solving. It can also support students preparing for AMC 8, Honors mathematics, or STEM-oriented study. A placement test is required before enrollment. Students transitioning from the specified Pre-Algebra, Algebra I, or AMC 8 Basics courses do not need to test again.
The Geometry placement test contains 16 questions and has a 40-minute time limit. The listed passing threshold is 60%, or approximately 10 to 11 correct answers. Questions cover geometry, equations and inequalities, analytic geometry, number theory, square roots, exponents, ratios, rates, unit conversion, percentages, counting, probability, and other reasoning. The AMC 8 Basics A placement test also lists 16 questions, a 40-minute limit, and a 60% threshold. The placement result is used to identify the appropriate course path before enrollment.
The course contains 18 lessons delivered once per week over one semester. Each lesson lasts 90 minutes and combines explanation, guided practice, advanced instruction, and review. A typical session includes a five-minute warm-up, 45 minutes of core instruction and guided practice, a five-minute break or activity, 30 minutes of advanced instruction, and a five-minute summary. Classes are conducted in English with English homework and supplementary resources. Live instruction is supported by recorded playback for later review.
The sequence begins with parallel lines, angles, triangle relationships, congruence, isosceles and equilateral triangles, perimeter, and area. It then moves through similarity, right triangles, bisectors, quadrilaterals, sectors, circular segments, angles in circles, and tangent lines. Later lessons cover solid geometry, analytic geometry, and two trigonometry lessons that include the Laws of Sines and Cosines. The course also connects visual figures to algebraic expressions, coordinates, ratios, and proofs. These topics match the supplied AMC 8-relevant skills list and the Geometry course outline.
The supplied course information does not provide a specific Geometry price. ACE Academy lists a placement test as required before enrollment, and the course materials state that a refund is available after the trial lesson according to the course policy. The Geometry trial class is identified as temporarily unavailable in the supplied information, with an expected launch in Q2 2026. Families can use the contact page to ask about current trial availability, placement, and enrollment details. The company also provides a free-trial pathway through its trial booking link, but availability may depend on the current program schedule.
The course covers standard Geometry content such as triangles, quadrilaterals, circles, area, analytic geometry, and trigonometry. It also uses AoPS materials and international competition thinking, which adds non-routine problem solving to the academic sequence. Students practice translating diagrams into equations, ratios, coordinates, and proof structures. That combination supports school achievement while developing the reasoning used in AMC-style problems. The course is therefore positioned for students who want systematic school support, competition preparation, or both.
Start with placement, build the foundations, and practice the reasoning that makes AMC 8 geometry less intimidating.
