Question

construct a triangle ECD with EC = ED = 6.8cm,CD = 5.6 cm. what is special name is given to such triangle

Answer 1

Answer:

isosceles triangle

Step-by-step explanation:

EC=ED=6.8cm------two-sides-are-equal

isosceles triangle

An isosceles triangle therefore has both two equal sides and two equal angles

Answer 2

Answer:

The required triangle is drawn in the attachment.

STEPS:

• Draw a line segment CD = 5.6cm.

• Taking C as a point, draw an arc of 6.8cm.

• Similarly, Taking D as a point, draw an arc of 6.8 cm which intersects the arc draw by point C.

• Both arcs interest at a particular point E.

• Join CE and DE.

• DE = CE = 6.8cm.

Hence:

• ∆ECD is the required triangle.
• The triangle is isosceles triangle because 2 sides of a triangle are equal and other one side is different.
