The measures of
∠A=120° and the
The pairs of measures of ∠H
opposite angles =120°; also measure
are ∠ A and ∠ H; of ∠M = 60° and the
∠ M and ∠T. measure of ∠T=60°.
∠A + ∠T = 120°+60° = 180°
∠ T + ∠H = 60°+120° = 180°
∠M + ∠H = 60°+120° = 180°
∠A + ∠M = 120°+60° = 180°
Diagonals are WR
and OD which
intersect at point A.
OA ≅ DA
WA ≅ RA
3. Mia can build the frame for a book case. How could she
use the properties of quadrilaterals to position the
shelves so that they are parallel to the base of the frame?
