Front

What is a scalene triangle?

Back

A scalene triangle is a triangle with no congruent sides.

Front

What characterizes an acute triangle?

Back

An acute triangle has all angles that are less than 90°.

Front

What is the measure of an angle in a triangle if the options are 180, 70, 54, 56 and the correct answer is 56?

Back

The measure of the indicated angle is 56.

Front

What is an exterior angle in relation to a triangle?

Back

An exterior angle is formed by one side of a triangle and the extension of an adjacent side.

Front

How do you solve for x in a given equation?

Back

To solve for x, isolate x on one side of the equation using algebraic operations.

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°.

Front

Define a right triangle.

Back

A right triangle is a triangle that has one angle equal to 90°.

Front

What is a corresponding angle?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the difference between acute and obtuse angles?

Back

Acute angles are less than 90°, while obtuse angles are greater than 90° but less than 180°.

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.
