Q1. A suspension footbridge has a triangular support frame whose base cable is 16 m long, and a maintenance walkway runs between the midpoints of the two inclined cables; what is the walkway length in m?
- A.8
- B.32
- C.16
- D.4
Answer: A. 8
By the Mid-Point Theorem the segment joining the midpoints of two sides equals half the third side, so the answer = 16/2 = 8.
Q2. A child builds a triangular kite whose bottom spar is 24 cm across and fixes a thin batten connecting the midpoints of the two upper spars; what is the batten length in cm?
- A.24
- B.12
- C.48
- D.6
Answer: B. 12
By the Mid-Point Theorem the segment joining the midpoints of two sides equals half the third side, so the answer = 24/2 = 12.
Q3. A carpenter braces a triangular gable whose base plank is 30 cm long by nailing a strip between the midpoints of the two rafters; how long is the strip in cm?
- A.15
- B.30
- C.7.5
- D.60
Answer: A. 15
By the Mid-Point Theorem the segment joining the midpoints of two sides equals half the third side, so the answer = 30/2 = 15.
