true or false ? perpendicular lines intersect at an angle of 45
True
FALSE because a rectangle has 4 right angles.
TRUE
True
True
False .According to laws of reflection, the angle of incidence is always equal to the angle of reflection.
It is true
True. The angle of reflection is equal to the angle of incidence when a wave is reflected off a surface. This is known as the law of reflection.
true or false
True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
Yes, it is true that angle 60 degrees has two edges in the angle parts.
It is false.
false
False
False. There are infinitely many angles at the centre of the circle.
True.
A right angle triangle can be scalene. Such a triangle has one right angle, two other unequal angles and no equal sides
