Answer to Problem 2PSA
Given triangle is scalene triangle
Explanation of Solution
Given information Given triangle has sides as 8 units, 9 units and 10 units
Since all the sides of given triangle are unequal
Hence given triangle is scalene triangle
b
The type of the given triangle
b

Answer to Problem 2PSA
Given triangle is isosceles triangle
Explanation of Solution
Given information Given triangle has two sides equal
Since triangle has two sides equal.
Hence, given triangle is isosceles
c.
The type of the given triangle
c.

Answer to Problem 2PSA
Given triangle is equilateral triangle
Explanation of Solution
Given information Since all sides of triangle are equal to 7 units
Hence given triangle is equilateral
d
The type of the given triangle
d

Answer to Problem 2PSA
Given triangle is scalene triangle
Explanation of Solution
Given information
Given triangle has sides its as:
AB > AC
And AC > BC
Since sides of the given triangle are given as,
AB > AC
And AC > BC
i.e., all sides are unequal
Hence,
Given triangle is scalene
e
The type of the given triangle
e

Answer to Problem 2PSA
Given triangle is scalene triangle
Explanation of Solution
Given information
Sides of given triangle are unequal
Since sides of given triangle are
x units, (x − 1) units and (x + 2) units
These all sides are unequal
Hence
Given triangle is scalene triangle
f
The type of the given triangle
f

Answer to Problem 2PSA
Given triangle DEF is isosceles triangle
Explanation of Solution
Given information Sides of given triangle DEF are given by
DE < DF
EF = DE
Since, two sides, EF and DE, of given triangle DEF, are equal
Hence, given triangle DEF is isosceles triangle
