Question


A triangle ABC with sides BC =7cm, ∠B=45∘,∠A=105∘ is given. The image of constructing a similar triangle of ΔABC whose sides are 34 times the corresponding sides of the ΔABC is given below.
A Triangle ABC With Sides BC =7cm, ∠B=45∘,∠A=105∘ Is...
The condition used to draw A'C' parallel to AC:


Options:
A .   Corresponding angles are equal
B .   Alternate interior angles are equal
C .   Co-interior angles are supplementary
D .   Perpendicular bisector theorem
Answer: Option A
:
A
A Triangle ABC With Sides BC =7cm, ∠B=45∘,∠A=105∘ Is...
Here we use the principle that when corresponding angles are equal, the lines are parallel.
∠A′C′B=∠ACB→ AC||A'C'.
