A. What is congruence?

Congruence is a mathematical term used to describe two figures that are the same size and shape. Two figures are said to be congruent if they can be transformed into one another through a series of rotations, reflections, and/or translations.

B. What is the definition of congruent triangles?

Congruent triangles are two triangles that have the same size and shape. They are said to be congruent if the corresponding sides and angles of the two triangles are equal.

Part 2: Identifying Congruent Triangles

A. What is the Side-Side-Side (SSS) Postulate?

The Side-Side-Side (SSS) Postulate states that if three sides of one triangle are equal to the three corresponding sides of another triangle, then the two triangles are congruent.

B. What is the Angle-Side-Angle (ASA) Postulate?

The Angle-Side-Angle (ASA) Postulate states that if two angles and the included side of one triangle are equal to the corresponding angles and included side of another triangle, then the two triangles are congruent.

Part 3: Using Congruent Triangles

A. How can congruent triangles be used to solve problems?

Congruent triangles can be used to solve problems in geometry by providing information about the length, angles, and size of the figures. By comparing the corresponding parts of two congruent triangles, you can determine the measurements of the sides and angles of the triangles. This can be used to solve problems involving triangles, such as finding the area of a triangle or the length of a side.

B. What is the Triangle Proportionality Theorem?

The Triangle Proportionality Theorem states that in any triangle, the ratio of the lengths of two sides is equal to the ratio of the lengths of the corresponding altitudes. This theorem can be used to solve problems involving triangles, such as finding the area of a triangle or the length of a side.

Answers:

A. Congruence is a mathematical term used to describe two figures that are the same size and shape.

B. Congruent triangles are two triangles that have the same size and shape.

A. The Side-Side-Side (SSS) Postulate states that if three sides of one triangle are equal to the three corresponding sides of another triangle, then the two triangles are congruent.

Side 1:

Side 2:

Side 3:

Triangle B:

Side 1:

Side 2:

Side 3:

3. Now, measure the angles of each triangle and note down the measurements in the table below.

Triangle A:

Angle 1:

Angle 2:

Angle 3:

Triangle B:

Angle 1:

Angle 2:

Angle 3:

4. Now, compare the sides and angles of both the triangles.
