Question 3
Maharashtra Board Solution
Draw, an obtuse-angled triangle and a right-angled triangle. Find the points of concurrence of the angle bisectors of each triangle. Where do the points of concurrence lie?
Solution & Step-by-Step Answer:
The points of concurrence of the angle bisectors of both the triangles lie in the interior of the triangles.
Question 4
Maharashtra Board Solution
Draw a right-angled triangle. Draw the perpendicular bisectors of its sides. Where does the point of concurrence lie?
Solution & Step-by-Step Answer:
The point of concurrence of the perpendicular bisectors of the sides of the right angled triangle lies on the hypotenuse.
Question 5
Maharashtra Board Solution
Maithili, Shaila and Ajay live in three different places in the city. A toy shop is equidistant from the three houses. Which geometrical construction should be used to represent this? Explain your
Solution & Step-by-Step Answer:
Solution: Since, Maithili, Shaila and Ajay live in three different places, lines joining their houses will form a triangle. The position of the toy shop which is equidistant from three houses can be found out by drawing the perpendicular bisector of the sides of the triangle joining the three houses. The shop will be at the point of concurrence of the perpendicular bisectors.
