## Division Of A Line Segment Into A Given Ratio

Division Of A Line Segment Into A Given Ratio Given a line segment AB, we want to divide it in the ratio m : n, where both m and n are positive integers. To help you to understand it, we shall take m = 3 and n = 2. Steps of Construction: 1. Draw any ray AX, making an acute angle with AB. 2. Locate 5(= m + n) points A1, A2, A3, A4 and A5 on AX so that AA1 = A1A2 = … [Read more...] about Division Of A Line Segment Into A Given Ratio

## How Do You Construct An Angle With Compass And Ruler

Construction Of An Angle Using Compass And Ruler To draw an angle equal to a given angle Given: An angle CAB. To construct: An angle RPQ equal to ∠CAB. Step 1: Taking A as the centre and any convenient radius, draw an arc cutting the arms of ∠CAB at points D and E. Step 2: Draw a ray PQ, with P as the centre and the same radius as above, draw an arc cutting the … [Read more...] about How Do You Construct An Angle With Compass And Ruler

## Construction Of Similar Triangle As Per Given Scale Factor

Construction Of Similar Triangle As Per Given Scale Factor Scale factor means the ratio of the sides of the triangle to be constructed with the corresponding sides of the given triangle. This construction involves two different situations : (i) The triangle to be constructed is smaller than the given triangle, here scale factor is less than 1. (ii) The triangle to be … [Read more...] about Construction Of Similar Triangle As Per Given Scale Factor

## How To Construct A Triangle With A Compass And Protractor

Construction of an Equilateral Triangle Steps of construction Step I: Draw a ray AX with initial point A. Step II: With centre A and radius equal to length of a side of the triangle draw an arc BY, cutting the ray AX at B. Step III: With centre B and the same radius draw an arc cutting the arc BY at C. Step IV: Join AC and BC to obtain the required … [Read more...] about How To Construct A Triangle With A Compass And Protractor
