Area of the triangle ADC- 5x5x6 = 15 sq. cm
Area of the triangle BDC = 5*5*6= 15 sq. cm
Ratio of areas of these triangles
15:15 - 1:1
Ratio in which CD divides AB is 5:5=1:1​

Answer 1

 

ANSWER:

In △PQR, ∠Q = 90∘ (a right angle)

Therefore, △PQR is a right angle traingle.

In △XYZ, ∠Y = 125∘ (an obtuse angle)

Therefore, △XYZ is an obtuse angle traingle.

In △LMN, all angles are acute angles.

Therefore, △LMN is a acute angle traingle.
