Questions and Answers

Congruent triangles have the same shape but not necessarily the same size.

True

In a triangle, if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, the two triangles are congruent.

True

If two corresponding sides of two triangles are congruent, then the triangles are congruent.

False

In a triangle, if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the two triangles are congruent.

Match the congruent triangle postulate with its description:

Side-Angle-Side (SAS) Postulate = If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the two triangles are congruent. Angle-Side-Angle (ASA) Postulate = If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, the two triangles are congruent. Hypotenuse-Leg (HL) Postulate = If the hypotenuse and a leg of one right-angled triangle are congruent to the hypotenuse and a leg of another right-angled triangle, the two triangles are congruent. Side-Side-Side (SSS) Postulate = If all three sides of one triangle are congruent to all three sides of another triangle, the two triangles are congruent. Signup and view all the answers

Match the following terms related to congruent triangles with their definitions:

Congruent Triangles = Triangles that have exactly the same size and shape. Corresponding Parts = Matching parts of congruent triangles, including sides and angles. CPCTC = An acronym for 'Corresponding Parts of Congruent Triangles are Congruent', a theorem used to prove other parts of triangles congruent.
