1.

Measure the sides of the following triangles in centimeters, using a divider and ruler. Enter the lengths in the table below. What do you observe?In ∆ABCIn ∆PQRIn ∆XYZl (AB) = cml (QR) = cml (XY) = cml (BC) = cml (PQ) = cml (YZ) = cml (AC) = cml (PR) = cml (XZ) = cm

Answer»

In ∆ABC	In ∆PQR	In ∆XYZ
l (AB) = 2.6 cm	l (QR) = 2.8 cm	l (XY) = 2.8 cm
l (BC) = 2.6 cm	l (PQ) = 3.8 cm	l (YZ) = 2.6 cm
l (AC) = 2.6 cm	l (PR) = 3.8 cm	l (XZ) = 4.3 cm

We observe that,

1. ∆ABC is an equilateral triangle,

2. ∆PQR is an isosceles triangle, and

3. ∆XYZ is a scalene triangle.
