Performance Task: Constructions — Unit test Answers

Angles 1 and 2 are supplementary.

Which best describes the dimensions of a plane?

3 lines are shown. A line with points P, R, N intersects a line with points M, R, O at point R. A line extends from point R to point L between angle P R M.

2 lines connect to form a right angle. A third line extends between the 2 lines to form 2 angles which are labeled 1 and 2.

Angle MON is a straight angle and bisects MOQ.

3 lines are shown. A line with points M, H, K intersects a line with points J, H, L at point H. A line extends from point H to point P between angle K H J. Angle M H L is 140 degrees and angle K H P is 20 degrees.

A line contains points M, N, O, P, Q, R, S with arrows instead of endpoints.

Given: AB = BCProve: B is the midpoint of AC.

Two lines extend from point S to create a right angle. The vertical line extends from point S through point R. The horizontal line extends right from point S through point T. A third line extends right and up from point S through point U.
