What is construction according to maths?

more To draw a shape, line or angle accurately using a compass and straightedge (ruler). Sometimes you are also allowed to use a protractor and triangle.

How do you justify a construction class 9?

We can justify the construction by showing ABC as an equilateral triangle i.e., AB = BC = AC = 5 cm and ∠A = ∠B = ∠C = 60°. In ΔABC, we have AC = AB = 5 cm and ∠A = 60°. From equations (1) and (2), ΔABC is an equilateral triangle.

What are the steps in construction class 9?

Steps of Construction :

1. Draw the base BC and at B make an angle XBC equal to the given angle.
2. Cut the line segment BD equal to AC — AB from the line BX extended on opposite side of line segment BC.
3. Join DC and draw the perpendicular bisector, say PQ of DC.
4. Let PQ intersect BX at A. Join AC (see fig.)

Is justification necessary for construction?

In construction justifying your steps is not required. The main concern is to get your steps clear and carrying out the construction with accurate measurement and labeling the diagram correctly.

What is a construction in math?

“Construction” in Geometry means to draw shapes, angles or lines accurately. These constructions use only compass, straightedge (i.e. ruler) and a pencil.
