Answers
Step-by-step explanation:
Equadrilateral triangle:
A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners).
- Area: ½×diagonl×(sum of perpendicular height)
- Perimeter: sum of side of the quadrilateral.
- Sum of interior angle: 360°
Isosceles Triangle:
An isosceles triangle is a triangle that has at least two congruent sides. The congruent sides of the isosceles triangle are called the legs. The other side is called the base. The angles between the base and the legs are called base angles. The angle made by the two legs is called the vertex angle. One of the important properties of isosceles triangles is that their base angles are always congruent. This is called the Base Angles Theorem.
- Area: ½×base×height
- Line of symmetry: 1
Scale Triangle:
A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180°.
