Vertical Angles
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
A rhombus has a pair of equal acute angles opposite one another. The other two angles are supplementary to these and so are also equal.
Yes it has 2 equal opposits acute and 2 equal opposite obtuse angles and they add up to 360 degrees
An isosceles triangle has two equal sides, and if one of the angles is 90 degrees, than the other two have to be equal. A triangle's angles always add up to 180 degrees, so the other two have to be 45 degrees.
right angle
Congruent angles. are you cheating on your geometry homework?
Vertical angles. These are two angles who, together, form two pairs of opposite rays. This means that these two angles form two lines that intersect. These angles have to be equal.
It is 'b' because the 4 interior angles of a square are all equal right angles
Vertical Angles are a pair of nonadjacent anglesopposite each other formed when two lines cross.Vertical angles are two angles opposite of each other. Vertical angles will also always have equal angles.
isosceles -2 equal sides, 1 other length side, 2 equal angles, 1 other angle scalene -all angles and sides different equilateral -all sides and angles same (angles always 60degrees)
Angles are equal or congruent to each other when the measurements of the angles are the same.
Intersecting lines form two sets of angles. The angles opposite each other are always equal.
Four (4) angles is inside a rhombus. Two of them is equal, and the other two is equal too, as well. All four is always add up to 360 degrees.

That is just how we define a square. Four equal sides that is connected at right angles to each other.
