Question

Construct a right angled triangle ABC such that BC=4 cm and AB=3 cm. Find the length of AC also

Answer 1

Answer:

Pythogoras theorem states that:

{ Hypotenuse } = { base (2) + height(2) }

where base and height are the 2 sides

Plugging in the values for the formula,

{ Hypotenuse } = { 4 (2) + 3 (2)

= /16 +9 = 25 = 5

Answer 2

$\dashrightarrow$ Steps :-

• First, draw a line segment BC of 4 cm.
• Next, take a protractor and keep it's mid-point on the point B and draw a ray measuring 90°.
• Then, take a compass and keep it's tip on the point B and draw an arc on the ray.
• Now, join the point C to the point where the arc and the ray meets. Name it as point A.
• Finally, the triangle is constructed.
• Measure the length of AC.

$\dashrightarrow$ Instruments used :-

• Ruler :- The ruler is used to draw the line segments and also the drawn lines should be straight always.
• Protractor :- The protractor is used to draw the rays of accurate measurements of degrees. It's also used to measure the angles given.
• Compass :- The compass is used to draw the arcs of accurate measurements as given in the question.
