Question

What is the measure of zSRT?

Answer 1

90 degree

Explanation:

We start with SWV as right angle and isosceles can be found to find W

SWV = 90 so we know as isosceles they all are 90 degree met with 45 degree at line of intersections.

We see a right angle at point S on SWT and make a right angle triangle at SWT, to find T angle equal to S=90 W=45 T=45

So SWT = SRT = SRW = TRV

The middle points with R in them are all 90 at point R

The others are 90 at point S on TSW (SWT) and on all outside perimeters for the larger triangles.
