A, commutative
Step-by-step explanation:
Commutative property means that you can switch around the numbers, and get the same answer. However, the commutative property is only compatible for addition and multiplication. I.e. 2+6 equals 6+2, but 2-6 does not equal 6-2.
Answer:
yes, this is a triangle. It is a right triangle
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
27+90+63 = 180
180=180
This is true so it is a triangle.
Because one of the angles is 90 degrees, it is a special type of triangle called a right triangle.
Step-by-step explanation:
