Question

Observe the figure and complete the following activity.

In fig, ∠B = 75°, ∠D = 75°

∠B ≅ `square`   ...[each of 75°]

∠C ≅ ∠C   ...`square`

ΔABC ~ Δ `square`   ...[`square` similarity test]

Answer 1

In fig, ∠B = 75°, ∠D = 75°

∠B ≅ \[\boxed{∠\text{D}}\]   ...[each of 75°]

∠C ≅ ∠C   ...\[\boxed{[\text{Common angle]}}\]

ΔABC ~ Δ\[\boxed{\text{EDC}}\]   ...[\[\boxed{\text{AA}}\] similarity test]]
