Triangle $PQR$ is an isosceles triangle with $PQ=PR$. Given that the angle bisector at $Q$ meets $PR$ at $A$ and that $QR=QA+PA$. Find angle $P$.
To find the measure of angle P in an isosceles triangle $PQR$, first identify the base angles of the triangle. These angles are equal in measure. Then, use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle P. Subtract the sum of the base angles from 180 degrees to find the measure of angle P.
No, angle P in an isosceles triangle $PQR$ must always be between 0 and 180 degrees. This is because the sum of the angles in a triangle is always 180 degrees, and the base angles of an isosceles triangle are always equal. Therefore, angle P cannot be larger than 180 degrees or smaller than 0 degrees.
If you don't know the measure of the base angles in an isosceles triangle $PQR$, you can use the fact that the base angles are equal to each other. Let x be the measure of one of the base angles. Then, the measure of angle P will be 180 - 2x degrees. You can then solve for x by setting this expression equal to the known measure of angle P.
No, the Pythagorean Theorem cannot be used to find the measure of angle P in an isosceles triangle $PQR$. The Pythagorean Theorem only applies to right triangles, and an isosceles triangle can only have one right angle if it is also equilateral. In general, the Pythagorean Theorem cannot be used to find the measure of angles in a triangle.
No, the position of angle P in the isosceles triangle $PQR$ does not affect its measure. As long as the triangle is isosceles, angle P will always have the same measure. The position of angle P may change if the triangle is rotated or reflected, but its measure will remain the same.
