A parallelogram
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.
No there isn't
A rhombus is a geometric shape, a diamond is not. 'Diamond' is from decks of cards, 'Rhombus' is from Math. BTW, a rhombus is a parallelogram* with opposite acute** and obtuse*** angles and all four sides are the same length.*opposite sides of the shape are parallel** less than 90∘***more than 90∘
An iscoceles triangle that is either obtuse or acute
no.out of it's 4 angles,2 are acute and the other 2 are obtuse.
2 obtuse and 2 acute in the classic kite shape.
An equalateral triangle
A rhombus (diamond shape as shown on playing cards) matches the question.
An obtuse triangle or an isosceles triangle if the 2 acute angles are equal in size
A parallelogram
A square
"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse
A rhombus is a equalateral quadrilateral. It is a leaning square or a side ways diamond.
Triangles:)
A trapezoid.
