Question

put a tick if all triangle is possible with the given condition and a cross if it is not. 1.two angles are right angles​

Answer 1

Answer:

x

Step-by-step explanation:

no, a triangle cannot be formed with two angles being right angles (=90°)

according to angle sum property, all the angles of a triangle sum upto 180°.

let the three angles of a triangle be angle A, angle B and angle C.

according to the question,

angle A= 90°

angle B= 90°

therefore,

angle A+ angle B + angle C= 180°

=> 90°+90°+ angle C = 180°

=> angle C = 180°-90°-90°

=> angle C = 0°

an angle in a triangle cannot be of measure 0°.

hence there cannot be a triangle with two angles measuring 90° (i.e., right angles)
