## How do you construct a triangle for construction?

Constructing triangles given SSS

1. Draw the longest side using a ruler.
2. Open the pair of compasses until they are 5 cm wide. Use a ruler to measure it. Draw an arc from point H above the line.
3. Open the pair of compasses until they are 3 cm wide. Use a ruler to measure it.
4. Join the arc to the points H and J using a ruler.

What are geometric constructions?

Definition of geometrical construction : construction employing only straightedge and compasses or effected by drawing only straight lines and circles —opposed to mechanical construction.

What are the types of constructions in geometry?

The Six Basic Constructions

• Copying a line segment.
• Copying an angle.
• Creating a perpendicular bisector.
• Creating an angle bisector.
• Creating parallel lines.
• Creating a perpendicular line through a given point.

### How do you draw geometric constructions?

Construction Steps

1. Draw segment a = AB between points A and B.
2. Construct perpendicular line b to segment AB through point B.
3. Construct circle c with center B through point A.
4. Intersect circle c with perpendicular line b to get intersection point C.
5. Construct perpendicular line d to segment AB through point A.

How do you construct a triangle like a triangle?

Case 1

1. Step 1: Construct a triangle ABC as given below:
2. Step 2: Draw a ray BX making an acute acute with the base BC and mark 5 points B1, B2, B3, B4, B5 on BX such that BB1 = B1B2 = B2B3 = B3B4 = B4B5.
3. Step 3: Join B3C and draw a line B5C’ such that B3C is parallel to B5C’, where C’ lies on the produced BC.

## Why are constructions important in geometry?

Geometric constructions help us to draw lines, angles, and shapes with simple tools.
