Answer 2

Answer:

there are 4 basic properties

• commutative
• associative
• identity
• distributive property of multiplication over addition

Explanation:

eg 5+7=7+5(commutative)

9*2=2*9(commutative)

(9+1)+2=(9+2)+1(associative)

15+0=15(Identity property )

3(4+5)=3(4)+3(5)(distributive property of multiplication over addition

2 ans- types of triangle are as follows

1. equilateral -when all sides and angles are equal then it is called as equilateral triangle
2. isosceles - when two angles and two side are equal then it is called as an isosceles triangle
3. scalene triangle-when none of the side or angle is equal then it is called as scalene triangle
4. right angled triangle - when the angle is 90°then it is called as right angled triangle
5. obtuse angled trangle -when the measure of angle is more than 90°then it is called as obtuse angled triangle
6. acute angled triangle-when the measure of angle is less than90°then it is called as acute angled triangle
