An isoceles triangle has only 2 equal sides and angles. An equilateral triangle has three of each. Any regular polygon has at least 2 equal sides and angles.
A trapezoid has 4 sides, 2 acute and 2 obtuse angles, and only one pair of parallel sides
A trapezoid (trapezium) has only 2 sides parallel and not all angles equal
Nothing, it's impossible.* * * * *Only if you limit yourself to quadrilaterals. But why? It is, of course, possible for a pentagon (or polygons with 6 or more sides) to have 4 equal sides and only 2 right angles.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
There is no quadrilateral that meets these requirements. It is, of course, possible for a pentagon (or polygons with 6 or more sides) to have 4 equal sides and only 2 right angles.
How about an isosceles triangle of which 2 of its 3 sides are congruent and 2 of its 3 angles are congruent
How about an isosceles triangle of which 2 of its 3 sides are congruent and 2 of its 3 angles are congruent
In an isosceles triangle 2 sides are congruent and 2 angles are congruent. In an equilateral triangle all 3 sides are congruent and all 3 angles are congruent also.
Any polygon with 4 or more sides can have only two right angles.
A pentagon has five sides and five angles, the only 2-D shape with these characteristics.
A square because that is the only possible figure that can have two congruent sides and four right angles.
