Identifying Perpendicular Lines: Analysis of a Quarter Circle Figure

Question

Are there two pairs of perpendicular lines in the figure?

00:00 Are there 2 perpendiculars in the drawing?

00:03 A perpendicular creates a right angle at the intersection point between the lines

00:07 Let's mark and count all right angles to find the perpendiculars

00:11 And this is the solution to the question

Remember that perpendicular lines form a 90-degree angle.

We will mark the intersection points of the lines with the letter T to work out if the angles are right angles, as follows:

From the drawing, it seems there are 2 right angles, which means there are indeed 2 pairs of perpendicular lines.
