The given figure shows an equilateral triangle ABC with each side 15 cm. Also `DE|\|BC, DF|\|AC, EG|\|AB` If DE + DF + EG = 20 cm, find FG.

The following figures shows a right - angled triangle ABC with angle B = 90 ^(@) , AB = 15 cm and AC = 25 cm. D is a point in side BC and CD = 7 cm. if De bot AC, find the length of DE.

The following figure shows a right-angled triangle ABC with /_B=90^(@),AB=15cm and AC=25cm.D is a point in side BC and CD=7cm. If DE perp AC, find the length of DE.

In two triangle ABC and DEF, AB= DE ,BC=DF and AC =Ef then

In the adjacent figure DeltaABC, D is the midpoint of BC. DE_|_AB, DF_|_AC and DE = DF . Show that DeltaBED ~= Delta CFD .

In the adjacent figure DeltaABC, D is the midpoint of BC. DE_|_AB, DF_|_AC and DE = DF . Show that DeltaBED ~= Delta CFD .

In the adjacent figure DeltaABC, D is the midpoint of BC. DE_|_AB, DF_|_AC and DE = DF . Show that DeltaBED ~= Delta CFD .

In the adjacent figure DeltaABC, D is the midpoint of BC. DE_|_AB, DF_|_AC and DE = DF . Show that DeltaBED ~= Delta CFD .

In the given figure, BC is parallel to DE. Area of triangle ABC = 25 cm^2 , Area of trapezium BCED = 24 cm^2 and DE = 14 cm . Calculate the length of BC. Also, find the area of triangle BCD.

In the given figure (not drawn to scale), Delta ABC, Delta EFG, Delta KIJ and Delta NMO are 4 different equilateral triangles. Find the perimeter of the figure, if side of square PDHL is 8 cm, AC = 4cm, EG = 2 cm, KI = 3 cm and MO = 2 cm.

Points D, E and F are the midpoints of sides AB, BC, and AC of DeltaABC . If DE = 10 cm, EF = 12 cm and DF = 8 cm, then find AB.
