Congruent and Similar Triangles Test

Front

What are congruent triangles?

Back

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

Front

What are similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

How do you find the perimeter of a triangle?

Back

The perimeter of a triangle is found by adding the lengths of all three sides.

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 parallel lines and transversals?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal and alternate interior angles that are also equal.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

How can you prove that two lines are parallel using angles?

Back

You can prove that two lines are parallel if the corresponding angles are equal or if the alternate interior angles are equal.

Front

What is the significance of an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are equal in length and all three angles are equal, each measuring 60 degrees.

Front

What is the relationship between the sides of similar triangles?

Back

In similar triangles, the lengths of corresponding sides are proportional.
