Answer 1

The step by step explanation is given below

Explanation:

In Δ INO and Δ GND

`\vec{NO} \cong \vec{ND}\ \textrm {given}\\\angle NIO \cong \angle NGD\ \textrm {given}\\\angle INO \cong \angle GND\ \textrm {reflexive}\\\triangle INO \cong \triangle GND\ \textrm {Angle Angle Side test}\\\angle D \cong \angle O\ \textrm {corresponding parts of congruent triangles}`
