A ΔABC can be constructed in

Question:

A ΔABC can be constructed in which ∠B =105°, ∠C = 90° and AB +BC + CA = 10 cm.

Solution:

False

Here, ∠B = 105°, ∠C = 90°

and AB + BC + CA = 10cm

We know that, sum of angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

Here, ∠B + ∠C = 105°+90°

= 195° >180° which is not true.

Thus, ΔABC with given conditions cannot be constructed.
