A The area of a right triangle is one half the base times the height.

B The Distance Formula calculates the distance between two points, not the coordinates of the midpoint of a line segment.

C The area of a right triangle is one half the base times the height. The Distance Formula calculates the distance between two points, not the coordinates of the midpoint of a line segment.

D Correct!

A The Midpoint Formula tells how to find the midpoint of a line segment, and the

Distance Formula tells how to calculate the distance between two points. If triangle PQR is isosceles, what are the coordinates of point R?

B The Midpoint Formula tells how to find the midpoint of a line segment, and the Distance Formula tells how to calculate the distance between two points.

19. ANS: C

Step 1: 2 is supplementary to the angle that is 117. 117 m2180. So m263.

Step 2: By the Alternate Interior Angles Theorem, 2 3. So m2m363.

Step 3: By the Isosceles Triangle Theorem, 2 and the angle opposite the other side of the isosceles triangle are congruent. Let 4 be that unknown angle.

Then, 2 4 and m2m463.

m1m2m4180 by the Triangle Sum Theorem. m163 63 180. So m154.

Feedback

A Angle 2 is supplementary to the angle that measures 117 degrees. B To find the measure of angle 1, use the Isosceles Triangle Theorem.

C Correct!

D By the Alternate Interior Angles Theorem, angle 2 is congruent to angle 3.
