Answer:
let the angles be x
the angles are same hence x+x=2x
therefore the sum of angles will be 2x
this implies that 90+2x=180(angle sum property)
2x= 180-90
2x, =90
x=45
therefore the two other angles are of 45 degree each

the sum of the measure of interior angles is 180. If x represent the measured of one of the congruent interior angles ,then 2x+90=180
represent the sum of the measurement of angles
may it helps u
