Question

9th maths 4.5 2nd sum construction​

Answer 1

Answer:

Question 2.

Draw and locate the centroid of the triangle ABC where right angle at A, AB = 4 cm and AC = 3 cm.

Solution:

In ∆ABC,

AB = 4 cm,

AC = 3 cm,

∠A = 90°

Construction:

Step 1 : Draw ∆ABC with AB = 4 cm, AC = 3 cm, ∠A = 90°

Step 2 : Draw perpendicular bisectors of any two sides (AB and AC) to find the mid points of AB and AC.

Step 3 : Draw the medians CD and BE. Let them meet at G.

Step 4 : G is the centroid of the given triangle.
