A bisected angle.
a line or supplementary angles.
you need the apex angle, call it n. Each base angle is one-half of (180 - n)
Rhombus
triangle isosceles triangle
A pentagon. If the sides and angles are equal it is a REGULAR pentagon.
a 'SCALENE' triangle. ; No equal sides, and no equal angles. An ISOSCELES triangle has two equal sides and two equal angles. An EQUILATERAL tringle has three equal sides and three equal angles all at 60 degrees. A RIGHT ANGLED triangle has one right angle (90 degrees) in it.
Such a rhombus is not possible as it would not have all its sides equal. Or you can keep all angles right angles and call it a square.
Opposite angles are equal, so:One of the angles can be anything between 0 and 180 degrees (exclusive). Call this "x".The opposite angle must be the same - also "x".The other two angles must be 180 - x.
you can call on ark angle Micheal for corage you can call on ark angle Micheal for corage you can call on ark angle Micheal for corage
a complementary angle
the angle is call and obtuse
Remote interior angles.
Remote interior angles.
Right Angle.
A polygon with four equal angles and sides is a square.
a line or supplementary angles.
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.
