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

How do you find the measure of an unknown angle in a triangle when two angles are known?

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the definition of an interior angle in a triangle?

Back

An interior angle is an angle formed by two sides of a triangle that meet at a vertex.

Front

If one angle of a triangle measures 34 degrees and another measures 38 degrees, how do you find the third angle?

Back

Add 34 and 38 degrees to get 72 degrees, then subtract from 180 degrees: 180 - 72 = 108 degrees.

Front

What is the relationship between the angles in a triangle?

Back

The angles in a triangle are related such that their sum is always 180 degrees.

Front

What is the formula to calculate the value of an angle in a right triangle?

Back

In a right triangle, the sum of the two non-right angles is 90 degrees.

Front

How do you determine the value of y in an equation?

Back

Isolate y on one side of the equation by performing inverse operations.

Front

What is the definition of a degree in terms of angle measurement?

Back

A degree is a unit of measurement for angles, where a full circle is 360 degrees.

Front

What is the significance of knowing the measures of angles in solving geometric problems?

Back

Knowing the measures of angles helps in determining unknown angles, solving for sides, and understanding the properties of shapes.

Front

What is the process for solving for x in an equation involving angles?

Back

Set up the equation based on the relationships between the angles and solve for x using algebraic methods.
