Explanation:
17. A regular hexagon, which means a hexagon with equal sides and equal interior angles, is the shape that has 3 pairs of parallel sides. Since PQ is parallel to BC, QR is parallel to CD, RS is parallel to DE, TS is parallel to FE, the angles of smaller hexagon are the same. Since both hexagons have the same angle at ∠A, all the angles are the same
(a) so CDE = QRS
(b) AT = 3PB
since AT = AP
if length of AB is 1, then length of AP is 3/4
so perimeter of larger hexagon is 6 x 1 = 6
perimeter of smaller hexagon is 6 x 3/4 = 4.5 or 4 1/2
18. If X is midpoint between A and Y and MX is perpendicular to AY just like BY, then M is midpoint between A and B so MX = 1/2BY
(a) BY = 2MX = 2(1.4) = 2.8
(b) In construction to build the A - frame houses as the frame helps to reflect the similarity due to similar triangles when the bar of the frame is placed parallel to the ground.
Hope this helps
