Q1. While drawing a four-sided kite on graph paper Farhan measures three of its corner angles as 87 deg, 92 deg and 91 deg; what is the measure of the fourth angle?
- A.100
- B.181
- C.90
- D.177
Answer: C. 90
The four interior angles of any quadrilateral add up to 360 deg. So fourth angle = 360 - (87 + 92 + 91) = 360 - 270 = 90 deg.
Q2. A glass tabletop is cut as a quadrilateral; a designer records three of its angles as 121 deg, 106 deg and 111 deg; what is the measure of the fourth angle?
- A.133
- B.143
- C.22
- D.158
Answer: C. 22
The four interior angles of any quadrilateral add up to 360 deg. So fourth angle = 360 - (121 + 106 + 111) = 360 - 338 = 22 deg.
Q3. On a survey sheet a four-cornered plot has three interior angles read off as 97 deg, 113 deg and 124 deg; what is the measure of the fourth angle?
- A.150
- B.26
- C.123
- D.154
Answer: B. 26
The four interior angles of any quadrilateral add up to 360 deg. So fourth angle = 360 - (97 + 113 + 124) = 360 - 334 = 26 deg.
