Review Unit 5 (Congruent Tri, Isos/Equil, Prove Tri Congnt Laws

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

Back

It means that line segment AB is perpendicular to line segment CB.

Front

What is the ASA congruence theorem?

Back

ASA stands for Angle-Side-Angle, a theorem stating that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the difference between an equilateral triangle and a scalene triangle?

Back

An equilateral triangle has all three sides equal, while a scalene triangle has all sides of different lengths.

Front

What does the HL theorem stand for?

Back

HL stands for Hypotenuse-Leg, a theorem used to prove the congruence of right triangles based on the lengths of the hypotenuse and one leg.

Front

How can you determine if two triangles are congruent using the SSS theorem?

Back

Measure the lengths of all three sides of both triangles. If all three pairs of corresponding sides are equal, the triangles are congruent.

Front

What is the definition of a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths.

Front

What does it mean for angles to be congruent?

Back

Congruent angles are angles that have the same measure.
