Triangles Test

Front

What is the definition of similar triangles?

Back

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

Front

What is the AA similarity postulate?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the SAS similarity theorem?

Back

If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What is the SSS similarity theorem?

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

How do you determine the order of sides in a triangle?

Back

The sides of a triangle can be ordered from longest to shortest based on the measures of the angles opposite those sides.

Front

What does congruent triangles mean?

Back

Triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What is the definition of a triangle's centroid?

Back

The centroid is the point where the three medians of a triangle intersect, and it is also the center of mass.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is the relationship between the angles and sides in a right triangle?

Back

In a right triangle, the side opposite the right angle is the hypotenuse, and the other two sides are the legs.

What is the Pythagorean theorem?
