Urgent question.
<OR is the bisector of right <TOS. Find m<TOR?

Last question:

<PT is the bisector of <APR. Identify two congruent angles:

a) <APR, <TPR
b) <APT, <APR
c) <APT, <RPT

Thanks.

Hello, swedishskinjer!

Are you really having trouble with these?

Quote:

$\displaystyle OR$ is the bisector of right angle $\displaystyle TOS.$
Find $\displaystyle m\angle TOR$

Code:

      S                |        R       |      *       |    *       |  *       | * ?       *-----------T     O

Just how big is half a right angle?

Quote:

$\displaystyle PT$ is the bisector of $\displaystyle \angle APR.$
Identify two congruent angles:

. . $\displaystyle a)\;\angle APR,\;\angle TPR\qquad b)\;\angle APT,\;\angle APR \qquad c)\;\angle APT,\;\angle RPT$

Code:

            A             /          T           /        *           /      *         /    *         /  *       / *       *------------------ R     P

$\displaystyle PT$ divides $\displaystyle \angle APR$ into two equal angles.

Can you find the two equal angles?
