If the inradius of a triangle with a perimeter of 60cm is 8 cm, then find the area of the triangle.(in cm2)
ABC is an equilateral triangle with sides of 24cm. Find the difference between its in-radius and circum-radius.
In ΔPQR, PQ = 4 cm, QR = 3 cm, and RP = 3.5 cm. ΔDEF is similar to ΔPQR. If EF = 9 cm, what is the perimeter of ΔDEF?
The area of a triangle is 480 cm² and the ratio of its sides is 10: 24: 26. What is the perimeter of the triangle?
Two sides of a triangle are 10 cm and 15 cm. Which of the following can be the third side of the triangle?
In a triangle, the lengths of two sides are 13 cm and 14 cm, and the included angle between them is 60°. Find the area of the triangle.
If in triangle ABC, If side AB=6√ 3, AC=12 and BC=6, then angle B equals:
