Answer:
In the given figure, AB∥CD and EF is a transversal, cutting them at G and H respectively. If ∠EGB=35°
and QP⊥EF, find the measure of ∠PQH.
We know that AB∥CD and EF is a transversal
From the figure we know that ∠EGB and ∠GHD are corresponding angles
So we get,
∠EGB=∠GHD=35°
From the figure we know that ∠GHD and ∠QHP are vertically opposite angles
So we get
∠GHD=∠QHP=35°
We know that the sum of all the angles in triangle DQHP is 35° .
We know that the sum of all the angles in triangle DQHP is 180°.
∠PQH+∠QHP+∠QPH=180°
By substituting the values we get
∠PQH+35°+90°=180°
On further calculation
∠PQH=180° −35° −90°
By subtraction
∠PQH=180° −125°
∠PQH=55°
Therefore, ∠PQH=55°
