Required Answer:-
Types of triangle:-
- Isosceles triangle
- Equilateral triangle
- Scalene triangle
Isosceles triangle: A triangle with at least two sides is equal.
Equilateral triangle: A triangle with all its sides equal.
Scalene triangle: If all the three sides of a triangle are unequal (if the sides are of different lengths).
Types of quadrilateral:-
- Trapezium
- Isosceles trapezium
- Parallelogram
- Rectangle
- Rhombus
Trapezium: A quadrilateral in which one pair of opposite sides are parallel whereas the other pair of opposite sides are non-parallel.
Isosceles trapezium: If the non-parallel sides of a trapezium are equal.
Parallelogram: A quadrilateral in which both the pairs of opposite sides are equal.
Rectangle: A quadrilateral in which every angle measures 90° (a right angle)
Rhombus: A quadrilateral in which all sides are equal. In a rhombus, diagonals bisect the angles at vertex.
More Information:-
A quadrilateral is a four sided closed figure.
The attached figure shows a quadrilateral ABCD and closed figure which has,
- Four sides : AB, BC, CD and DA
- Four verticles : vertex A, vertex B, vertex C and vertex D
- Four angles : ∠ABC, ∠BCD, ∠CDA and ∠DAB
- Four pairs of adjacent sides : AB and DC ; BC and CD ; DA and AD
- Two pairs of opposite sides : AB and DC ; BC and AD
A triangle is a plane closed figure bounded by three line segments.
In the attached figure, the line segments AB, BC and CA are the sides of the triangle ABC. (ΔABC)
