Congruent Triangles

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence.

Front

If ∆LMK ≅ ∆LMT, what can we conclude about ∠K?

Back

∠K ≅ ∠T, since corresponding angles in congruent triangles are equal.

Front

How would you classify a triangle with all sides of different lengths?

Back

A triangle with all sides of different lengths is called a Scalene triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence.

Front

Can two triangles be congruent if they only have two sides and a non-included angle equal?

Back

No, two triangles cannot be proven congruent by SSA (Side-Side-Angle) alone.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the SSS criterion for triangle congruence?

Back

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

Front

If two angles of one triangle are equal to two angles of another triangle, what can be said about the triangles?

Back

The triangles are congruent by the Angle-Angle (AA) criterion.

Front

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

Back

An isosceles triangle has at least two equal sides, while a scalene triangle has all sides of different lengths.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.
