as that of the blue triangle? How many of them have the
same measures of the blue triangle?​

Answer 1

continuation of the answer:

3. AB is parallel to CQ and AC is parallel to BQ .

So ABQC is a parallelogram.

So area of triangle ABC= area of triangle

BQC

Similarly , area of ABC= area of ACP = area of ABR

So there are 9 triangles
