How many angles can a rhombus have?
A rhombus has four equal sides, but it is not necessarily a square. Think of it as a square that can be stretched. Thus, it will have four angles and opposite angles will be the equal. A special case of a rhombus is a square and then, all four angles will be equal 90 degrees.
What does a rhombus have to have to prove that it is a rhombus?
a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
Is a rhombus a a parallelogram with all equal angles?
No. A rhombus is a parallelogram with all equal sides. A parallelogram with all equal angles is a rectangle (which might also be a rhombus and a square).
Is a rhombus a regular parallelogram?
No. In a regular polygon, all sides and all angles are equal. A rhombus has four equal sides but the angles don't have to be equal, so in general a rhombus is not a regular quadrilateral or a regular parallelogram. If the rhombus happens to have four equal angles, then it is a square, which would be a regular parallelogram.
When does a rhombus have equal angles?
A rhombus has two equal opposite acute angles and two equal opposite obtuse angles with all four angles adding up to 360 degrees.
