 Area of shades region square inches

Step-by-step explanation:

In the given figure accordingly, we have to find the Area of the shaded region

Area of shaded region= Area of big triangle - Area of the small triangle.

          Area of a  triangle=  

Altitude is the perpendicular height of the triangle from its top to base.

Base of big triangle=12 inches,    Altitude of big triangle=6+3= 9 inches

Area of Big triangle  

Base of small triangle= 6 inches,    Altitude of small triangle= 3 inches

Area of the small triangle=

        Area of shades region

                                              square inches

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.
