In the given figure , Find the distance AB.
ΔABC is a right angled triangle. Find the length of AC. Given that BC = 3 units; AB = 4 units.
In the adjoining figure, if BC=a units, AC=b units, AB=c units and ∠CAB=120∘, then prove that a2 = b2 + c2 + bc.
In the given figure, ABCD is a rhombus. If OB = 3 units, OC = 4 units and AE = 6.4 units. Find the length of CE. (CE is perpendicular to AB)
