Understanding Angles in a Rhombus

What is a defining characteristic of a rhombus?

• It is a type of triangle.

• All sides are congruent.

• All angles are right angles.

• It has no parallel sides.

What is true about consecutive angles in a rhombus?

• They are always obtuse.

• They are always equal.

• They add up to 90 degrees.

• They add up to 180 degrees.

What happens to opposite angles in a rhombus?

• They are supplementary.

• They are equal.

• They are always different.

• They add up to 90 degrees.

What effect does drawing a diagonal have on the angles of a rhombus?

• It creates obtuse angles.

• It splits the angles into two equal parts.

• It makes all angles equal.

• It changes the sum of the angles.

In the first example, if one angle is 106 degrees, what is the measure of the angle next to it?

• 180 degrees

• 106 degrees

• 74 degrees

• 37 degrees

In the second example, if an obtuse angle is 118 degrees, what is the measure of the opposite angle?

• 62 degrees

• 31 degrees

• 118 degrees

• 90 degrees

In the second example, what is the measure of angle 2 if the diagonal splits the angle into two equal parts?

• 118 degrees

• 90 degrees

• 62 degrees

• 31 degrees

In the third example, what angle is created by the intersection of two diagonals in a rhombus?

• 45 degrees

• 60 degrees

• 90 degrees

• 180 degrees

In the third example, if one angle is 58 degrees, what is the measure of the opposite angle?

• 58 degrees

• 32 degrees

• 180 degrees

• 90 degrees

In the third example, what is the measure of angle 1 if the sum of angles in the triangle is 180 degrees?

• 90 degrees

• 32 degrees

• 58 degrees

• 180 degrees
