What is a triangle?

Back

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the longest side of a triangle called?

Back

The longest side of a triangle is called the hypotenuse in a right triangle, and it is opposite the largest angle.

Front

What is the Angle-Side-Angle (ASA) postulate?

Back

The ASA postulate states that if two angles and the side between them in one triangle are equal to two angles and the side between them in another triangle, then the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) postulate?

Back

The SAS postulate states that if two sides and the angle between them in one triangle are equal to two sides and the angle between them in another triangle, then the triangles are congruent.

Front

What is the Side-Side-Side (SSS) postulate?

Back

The SSS postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the Angle-Angle (AA) similarity postulate?

Back

The AA similarity postulate states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

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

Back

The measure of an angle in a triangle can be determined using the properties of triangles, such as the sum of angles in a triangle being 180 degrees.

Front

What is the relationship between the sides and angles of a triangle?

Back

In a triangle, the larger the angle, the longer the opposite side; conversely, the smaller the angle, the shorter the opposite side.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface on which points are plotted and defined by a pair of numerical coordinates.
