Asection of a stained-glass window is shaped like a parallelogram its base is 6.5 inc and its height is 4 inc. how much glass is needed the section completely ?

26

Step-by-step explanation

to find the area of a parallelogram you need to multiply base times height, which in this case would be 6.5*4 would equal to 26

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
