10. Ifall the three angles of a triangle are of the same measure, find the measure of each of the angles​

Answer 1

Answer:

45°

Hope it will help you

Answer 2

Answer:

Step-by-step explanation:

IN AN ISOSCELES RIGHT ANGLED TRIANGLE , FIRST ANGLE = 90

          AND SECOND AND THIRD ANGLE ARE EQUAL ( LET CALL THESE ANGLES = x)

9) IN A TRIANGLE ,

SUM OF ALL THE ANGLES = 180

SO,

(1ST + 2ND+ 3RD) ANGLE =180

=) 90 + x +x = 180

=)90+ 2x =180

=)2x =180-90

=)2x= 90

=)x= 45

SO ALL THREE ANGLES ARE 90 , 45, 45

10)SUM OF ALL THE ANGLES A TRIANGLE = 180

SINCE ALL THE ANGLES ARE OF SAME MEASURE( LET CALL THEM y)

1ST ANGLE + 2ND ANGLE + 3RD ANGLE = 180

y+y+y = 180

3y = 180

y =60

SO ALL THE ANGLES OF THIS TRIANGLE = 60
