Question

In Figure AB||CD, EF||DQ. Determine the measures of Angle PDQ, Angle AED and Angle DEF.​

Answer 1

$\red{\boxed{\mathfrak\colorbox{grey}{Answer}}}$

∴∠AED = ∠CDP

→ ∠AED = 34°

Ray EF stands on AB at E.

∴ ∠AEF + ∠FEB = 180°

→ ∠AED + ∠DEF + ∠FEB = 180°

-- 34° + ∠DEF + ∠FEB = 180°

-- 112° + ∠DEF = 180° - 112° = 68°

Now,EF || DQ || and transversal PE intersects DQ at D andEF at E.

∴∠PDQ = ∠DEF

∠PDQ = 68°

Answer 2

Given : AB∣∣CD;EF∣∣DQ

To find : ∠PDQ

∵AB∣∣CD and PE is transversal

∠PDC and ∠PEA are corresponding angles.

∴PEA=34

∠PEA+∠PEF+∠FEB=180

(Linear pair) +∠PEF+∠FEB=180

∠PEF=180 −34 −78

∠PEF=68

∵EF∣∣DQ

∠PDQ=∠PEF=68

∴∠PDQ=68∘
