A triangle can have:
The area of a triangle ABC is 16 cm². If a similar triangle DEF has sides that are twice the length of ΔABC's sides, what is the area of ΔDEF?
From an outside point P, two tangents, PA and PB, are drawn to a circle. Given that the length of PA is 12 cm, what is the length of PB?
A circle is inscribed within a right triangle. Considering that the lengths of the two legs measure 6 cm and 8 cm, what is the radius of the inscribed circle?
