Solution
Let one of the complementary angle = x
Since, sum of the complementary angles = 90°
Then the other angle =  (90° – x)
As per the...

#### in figure abc is an isosceles triangle in which AB=AC



Given in ΔABC, AB = AC
⇒ ∠ABC = ∠ACB (Since angles opposite to equal sides are equal)
Also given that AD = AB
⇒ ∠ADC = ∠ACD (Since angles opposite t...

#### in a given figure / POR and / QOR form a leaner pair if a-b-=80 find the value of a and b.[lease its urgent i dont have time}



a - b = 80
a + b = 180
a = 80 + b
putting 80 + b in place of a
80 + b + b = 180
80 + 2b =180
2b = 180 - 80
2b = 100
b = 50
