What is a right isosceles triangle?

Back

A right isosceles triangle is a triangle with one 90-degree angle and two sides of equal length.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

How do you find the value of x in a triangle?

Back

To find the value of x, use the properties of triangles, such as the sum of angles in a triangle equals 180 degrees.

How do you name a triangle that is congruent to triangle CBA?

Back

A triangle congruent to triangle CBA can be named triangle ZYX, where the vertices correspond to the same angles.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside two parallel lines. They are equal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is an obtuse triangle?

Back

An obtuse triangle is a triangle that has one angle greater than 90 degrees.

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle with all sides of different lengths and all angles of different measures.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are equal.
