2-11.

Jerry has an idea. Since he knows that an isosceles trapezoid has reflection symmetry, he reasons, *“That means that it must have two pairs of angles with equal measure.”* He marks this relationship on his diagram below.

Copy the shapes below onto your paper. Similarly mark which angles must have equal measure due to reflection symmetry. Homework Help ✎

KITE

ISOSCELES TRIANGLE

REGULAR HEXAGON

RHOMBUS

Draw all lines of symmetry.

Mark the angles that correspond and are on opposite sides of the line of reflection.
