Imagine you're drawing a treasure map. You've marked where the treasure is with a 'point'. Now, you want to indicate the direction to start walking from the 'point'. You draw one ray pointing away from the 'point'. How many more rays do you need to draw to indicate another direction forming an angle with the first ray? (One ray has been provided for you)

• 3

• 7

• 4

• 1

Imagine you're drawing a circle on a piece of paper. What is the total degree measure of that circle?

• 360 degrees

• 480 degrees

• 510 degrees

• 120 degrees

What is the angle’s measure created by the 2 hands on the clock? (Remember a straight angle measures 180 degrees).

• 270 degrees

• 90 degrees

• 150 degrees

What are the corresponding angles when two parallel lines are cut by a transversal?

• Corresponding angles are complementary.

• Corresponding angles are equal.

• Corresponding angles are supplementary.

• Corresponding angles are always different.

Identify the vertical angles formed by the transversal and the parallel lines.

• The vertical angles are the angles adjacent to the transversal.

• The vertical angles are the angles formed by the intersection of two parallel lines.

• The vertical angles are the angles formed outside the parallel lines.

• The vertical angles are the pairs formed at the intersection of the transversal with the parallel lines.

If angle 1 is 60 degrees, what is the measure of angle 2, which is a vertical angle?

• 60 degrees

• 90 degrees

• 45 degrees

• 30 degrees
