Shape with 4 sides and 3 angles
WebbEvery triangle has 3 vertices, 3 angles that may or may not be equal: Example 2 – Quadrilateral: Draw a quadrilateral on the whiteboard and explain that a quadrilateral is a 2-dimensional figure that has 4 sides and 4 vertices. Add that a quadrilateral is just a flat figure with four sides, all of which connect up and are straight. WebbThere are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length. A triangle’s name also depends on the size of its inside angles: acute if all angles are less than 90°, right-angled if one angle is 90°, or obtuse if one angle is more than 90°.
