what is the perimeter of triangle abc? round the answer to the nearest tenth, if necessary.

12 units is the perimeter of triangle ABC.

Step-by-step explanation:

Coordinates of triangle ABC:

A = (-1,3), B = (3,6), C = (3,3)

Distance formula:

Distance of AB: A = (-1,3), B = (3,6)

Distance of BC: B = (3,6) , C = (3,3)

Distance of CA:  C = (3,3) , A = (-1,3)

Perimeter of the triangle ABC = AB +BC + CA

= 5 units + 3 units + 4 units = 12 units

12 units is the perimeter of triangle ABC.

i believe the answer is the polygon, heptagon.

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.
