An isoceles triangle has at least two sides equal; an equilateral has three sides equal so it is also isoceles; and since all angles are acute it is also an acute traingle
Not necessarily. Rectangles are quadrilaterals and have no acute angles.
No, because all quadrilaterals have 4 straight sides.
No.
No.
An isoceles triangle has at least two sides equal; an equilateral has three sides equal so it is also isoceles; and since all angles are acute it is also an acute traingle
Not necessarily. Rectangles are quadrilaterals and have no acute angles.
No. There are quadrilaterals that have no right angles.no,what about a trapizoid or rhombus
No.
Not all 4 sided quadrilaterals have lines of symmetry.
It is an isosceles triangle and an isosceles trapezoid
An isosceles triangle is one with at least two equal sides.
No, because all quadrilaterals have 4 straight sides.
No.

No
All quadrilaterals have 4 sides and 4 interior angles that add up to 360 degrees and some of the better known ones are:- 1 square 2 rhombus 3 rectangle 4 parallelogram 5 trapezoid or trapezium 6 isosceles trapezoid or trapezium 7 kite 8 arrowhead
