Hello!
By definition, the intercept of the 3 bisectors, within a triangle is the Incenter. So let's get started, by tracing three bisectors.
In the triangle PQR::
- Use a compass, open its legs with a little more than half of
. Place the needle point in the vertex of P. Mark! - Do the same, placing the needle point in Q, following
direction. Mark - Repeat it with the other triangle's line segment, namely:

4.Trace with a ruler, from each intersection point a line. You'll trace three lines then.
5. Place the compass' needle point in this intersection point, (inside the triangle) with a hinge up to the triangle side, draw the circle inscribed.
Answer:
C: ∠6 and ∠2
Step-by-step explanation:
Step 1:
∠6 = ∠9 S.S. Int. ∠'s (Same Side Interior ∠'s)
Step 2:
∠9 + ∠2 = 180° Sum of line
Step 3:
∠9 ≠ ∠2
Answer:
C: ∠6 and ∠2
Hope This Helps :)
Given:
First side(A): 2B - 7
Second side(B): B
Third side(C): B + 4
Plug in values:
A + B + C = 80
2B - 7 + B + B + 4 = 80
If you look at the coefficients only, you can rewrite the equation like this:
2B + B + B - 7 + 4 = 80
This means that 4B - 7 + 4 = 80
=4B - 3 = 80
= 4B = 80 + 3
B = 83/4, so you can either write B as 83/4 or as 20.75.
Checking your work:
A: 2(20.75) - 7 = 34.5
B: 20.75
C: 4 + 20.75 = 24.75
34.5 + 20.75 + 24.75 = 80cm.
Hope this helped.
