In geometry<span>, the </span>angle bisector theorem<span> is concerned with the relative </span>lengths<span> of the two segments that a </span>triangle<span>'s side is divided into by a line that </span>bisects<span> the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
</span>I believe that the answer is congruent

The correct answer is D. (2.4, -1)
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.
hope this helped :)
Given:
Area and altitude PS of ∆PQR are ar(∆PQR) = 180cm² and PS = 15.
To find:
The measure of side QR.
Solution:
According to the given information, PS is an altitude of ∆PQR. It means QR is the base of ∆PQR.
We know that, the area of a triangle is


Substituting the given values, we get



Divide both sides by 15.


Therefore, the measure of side QR is 24 cm.
