Question

justification of Right triangle whose base is 12 cm and sum of its hypotenuse and the other side is 18 cm
​

Answer 1

Answer:

Step-by-step explanation:

i) Draw BC = 12 cm.

(ii) Construct ÐCBY = 90°.

(iii) From ray BY, cut-off line segment BD = 18 cm.

(iv) Join CD.

(v) Draw the perpendicular bisector of CD intersecting BD at A.

(vi) Join AC to obtain the required  △ABC.

Justification

Since A lies on the perpendicular bisector of CD.

Therefore, AD = AC

Now,    BD = BA + AD

⇒    BD = AB + AC

Hence,  △ABC is the required triangle.
