Question

properties of 2d figure​

Answer 1

Hi my dear friend,

Properties of 2D Shapes

Square. • 4 equal sides • 4 equal angles (90°) • 4 axes of symmetry.

Rectangle. • 2 sets of 2 equal sides • 4 equal angles (90°) • 2 axes of symmetry.

Triangle. • Can have no, 2 or 3 equal sides • Can have no, 2 or 4 equal angles • Can have up to 2 axes of symmetry.

Circle. ...

Pentagon. ...

Hexagon. ...

Octagon. ...

Parallelogram.

~Thank you

⚫Circle:
A circle is a shape each point on which is equidistant from a fixed point called center and this fixed distance is termed as radius.

▶Formulas

♠Area = πr2πr2
♠Circumference = 2 π r

⚫Semicircle

The half of a circle is termed as a semicircle.

▶Formula

Area = 1/2 πr²πr²

Circumference = ππ rWhere, r is radius.

⚫Oval or ellipse

If the two perpendicular diameters of a circle are different It may also be called as an ellipse.

⚫Triangle
A triangle a plane figure that is bounded by three straight lines.

▶Formulas

♠Area = 1/2x base x height
Also
♠Area = s(s−a)(s−b)(s−c)−−−−−−−−−−−−−−−−−√s(s−a)(s−b)(s−c)
Where, a, b and c are sides of a triangle and s = semi perimeter = a+b+c2a+b+c2

⚫ Square
A square has four equal sides. It has four equal angles which measure 90 ∘

▶Formula
♠Area = (side) 22
♠Perimeter = 4 x side

⚫Rectangle
A rectangle is four sided 2-d shape which has two opposite sides equal. It also has four equal angles measuring 90 ∘

▶Formula
♠Area = Length x breadth
♠Perimeter = 2 x (length + breadth)

⚫) Parallelogram
A parallelogram does have four sides. The pair of opposite sides are equal and parallel to each other. Opposite angles are also equal.

▶Formula
♠Area = Base (one side) x Height
