Exam 3: Parallel Lines

In , m = 37 ° and m = 53 ° . What type of triangle is ?

What two qualities are needed in order that a polygon be classified as a REGULAR polygon?

For the triangle shown, what is the image of the reflection of the given triangle across ?

If r || s and m = 73 ° , find m .

If two parallel lines are cut by a transversal, then the interior angles on the same side of the transversal are:

Which statement is a corollary of the theorem, "The sum of the three interior angles of a triangle is 180°."

Find the measure of each interior angle of a regular octagon.

In the figure, a || b and transversal t . If   and   , find x .

In , m = 37 ° and m = 69 ° . Find m .

When two lines are cut by a transversal, and are one pair of alternate interior angles that are formed. If    and   , what relationship (in simplified form)exists between x and y ? Answer in the form x = .

Any transformation of a geometric figure produces an image that is congruent to thegiven geometric figure.

If r || s and m = 108 ° , then:

In (not shown), is a right angle. Where M is a point on and N is a point on , how are and related?

Use to find the total number of diagonals for a polygon with 10 sides.

Draw a conclusion based upon true statements (i.)and (ii.). (i.)If two triangles are congruent, then they are similar. (ii.) is not similar to .

The figure (a square)shown has exactly one line of symmetry.

Each interior angle of a regular hexagon measures 60°.

Suppose that lines r and s are both perpendicular to line t. Then r is parallel to s if:

A regular hexagon has a point of symmetry. What is the smallest measure for an angle of rotation that has the image trace (fall over)the given hexagon?

In , m = 37 ° and m = 116 ° . Find the measure of exterior angle RTV.
