Question

In triangle PQR, r^2 = p^2 + q^2.

Triangle PQR has sides p, q, r opposite to the corresponding vertices P, Q, R

Which equation is true about the measure of the angles of the triangle?

The measure of angle PRQ is equal to 100 degrees
The measure of angle PRQ is equal to 90 degrees
The measure of angle PQR plus the measure of angle QPR is equal to 80 degrees
The measure of angle PQR plus the measure of angle QPR is equal to 70 degrees

Answer 6

if we have a right triangle with side lengths a,b,c
and c is the longest side (opposite the 90 degree angle), then
\[\Large a^2 + b^2 = c^2\]
which is the pythagorean theorem

Answer 7

yes

Answer 8

the link doesn't work

Answer 9

how do you pot picture

Answer 10

Answer 11

hold on

Answer 12

`r^2 = p^2 + q^2` has `r^2` on its own side, so it's very similar to `c` in my post above

Answer 13

k

Answer 14

I think it's 90 degree angle, am I right?

Answer 15

yes R is the 90 degree angle

Answer 16

So B is the right answer?

Answer 17

`The measure of angle PRQ is equal to 90 degrees` is true, yes

Answer 18

alright thanks a bunch. ps. here is a medal.
