In `DeltaLMN`, LM=5cm, MN=3cm and LN=4cm. Then find biggest and smallest angles of `Delta LMN`.

In triangle LMN , LM=5cm , MN=3 cm and LN=4cm . Find biggest and smallest angle.

In trianglePQR, PQ=10cm, PR=5cm, QR=12cm . Find out the greatest and the smallest angle of triangle.

In right angled Delta LMN, angleM= 90^@ .If l(LM)=12cm and l(LN)=20cm, find the length of seg MN.

trianglePQR, PQ=12cm, QR=14cm, PR=8cm . Find out the greatest and the smallest angle of the triangle.

In triangle PQR , PQ =10 cm , QR =12 , PR =8 cm . Find out the greatest and the smallest angle of the triangle .

In fig.45,ABC,AB=3cm,BC=4cm and AC=5cm name the smallest and the largest angles of the triangle.

The side of two similar triangle Delta DEF and Delta LMN are 35 cm and 45 cm respectively, then find the ratio of the area of triangles.
