Geometry Angle Bisector Flashcard

Front

What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

If angle JHG measures 161 degrees, what are the measures of angles GHK and KHJ if they are equal?

Back

m∠GHK = 80.5 degrees, m∠KHJ = 80.5 degrees.

Front

What is the measure of angle A if it is given as 25 degrees?

Back

∠A = 25 degrees.

Front

If angle A measures 49 degrees, what is the measure of angle A in a triangle where the other angles are 90 degrees and 41 degrees?

Back

∠A = 49 degrees.

Front

What is the measure of angle CBD if angle ABC measures 34 degrees?

Back

m∠CBD = 34 degrees.

Front

How do you find the measure of an angle when given the measures of the other angles in a triangle?

Back

Use the triangle sum theorem: the sum of the angles in a triangle is always 180 degrees.

Front

What is the relationship between the angles formed by a transversal intersecting two parallel lines?

Back

The corresponding angles are equal, and the alternate interior angles are equal.

Front

If angle CP is undefined, what does that imply about the angle?

Back

It implies that the angle cannot be determined or is not applicable in the given context.

Front

What is the formula to calculate the measure of an exterior angle of a triangle?

Back

The exterior angle is equal to the sum of the two opposite interior angles.

Front

What is the measure of an angle if it is complementary to 90 degrees?

Back

The measure of the angle is 0 degrees.
