Question

Draw an acute angled Δ PQR. Draw all of its altitudes. Name the point of concurrence as ‘O’.

Answer 1

In order to construct an acute angle triangle we need to have all its interior angles lesser than 90 degree.

The construction is very easy first of all we have to draw a horizontal line of arbitrary length. Now from both the ends draw two acute angles. And the third will be acute as well.

Answer 2

Hi,

Solution: steps of construction

1. Draw the line QR of any length.
2. At Q draw an acute angle (i.e. greater then 0 degree and less then 90 degree),with the help of protector and scale.
3. draw a line from Q with the given angle ,mark the point P.
4. Join P and Q. Δ PQR is formed.
5. To draw altitudes , draw lines from all points i.e. PQR,join them with dashed lines.where all lines meet mark that point as O.

Hope it helps you.
