this is called vertical angles
Well, if one angle is acute then the other one has to be acute. This is because the definition of complimentary angles is the sum sum of the angles has to add up to 90 degrees. So therefore, the angle has to add up to 90 degrees.
3x + 4x + 5x = 180 12x = 180 x = 15 The angles are 45, 60 and 75
The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 degrees.
a right angle
The angle is 90 degrees.
Vertical Angles or 4
Opposite angles.
Two angles that aren't adjacent but are formed by intersecting lines are called vertical angles. Their angle measures are always equal.
Vertical angle (I think? I'm doing homework)
A side refers to one of the rays that form an angle. Vertical are also called opposite angles. They are nonadjacent angles formed by intersecting lines.
Vertical angles
Corgent Angles
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
When lines intersect, angle formed between them is Θ or 180-Θ.
Such angles are called vertically opposite angles.
Actually there are 4 angles formed by 2 intersecting lines, and as long as the lines are PERPENDICULAR, the angles are all right angles, 90 degree each.
