Geometry Final Review

Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle, a criterion for triangle similarity where two angles of one triangle are equal to two angles of another triangle.

Front

What is the point of concurrency where the medians of a triangle intersect?

Back

The point of concurrency where the medians of a triangle intersect is called the Centroid.

Front

What is an acute triangle?

Back

An acute triangle is a triangle where all angles are less than 90°.

Front

How do you find the measure of an angle in a triangle?

Back

To find the measure of an angle in a triangle, you can use the triangle sum theorem, which states that the sum of the angles in a triangle is always 180°.

Front

What is the measure of angle A if angle B is 44° and angle C is 96°?

Back

Angle A = 180° - (Angle B + Angle C) = 180° - (44° + 96°) = 40°.

Front

What is the Circumcenter of a triangle?

Back

The Circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect, and it is equidistant from the vertices of the triangle.

Front

What is the Incenter of a triangle?

Back

The Incenter is the point where the angle bisectors of a triangle intersect, and it is equidistant from the sides of the triangle.

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side, a criterion for triangle similarity where the lengths of the corresponding sides of two triangles are proportional.

Front

What is the Orthocenter of a triangle?

Back

The Orthocenter is the point where the altitudes of a triangle intersect.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is exactly 90°, and the sum of the other two angles is 90°.
