Either perpendicular lines or linear pairs I️t depends on which one you use. Perpendicular lines are lines in which one line goes straight through another and forms right angles. Transversals can be slanted which would form linear pairs
Answer: 3
Step-by-step explanation: your welcome even if im wrong
check the picture below.
notice, both pairs of opposite sides are parallel.
Answer:
radius = 10
Step-by-step explanation:
As AB is the diameter of the circle, the angle ACB inscribes an arc of 180 degrees, so it is a 90 degrees angle, then the triangle ACB is a right triangle, with hypotenusa AB.
We can find the length of the diameter AB using the Pythagoras' theorem:
AB^2 = CA^2 + CB^2
AB^2 = 12^2 + 16^2 = 400
AB = 20
The radius of the circle is half the diameter, so the radius is 20 / 2 = 10
