Answer:
simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
Step-by-step explanation:
<h3>Triangle 1 :</h3>
Classify by angle = <u>obtuse</u> (one angle in the triangle is obtuse)
Classify by sides = <u>isosceles</u> (has two equivalent sides)
<h3>Triangle 2 :</h3>
Classify by angles = <u>right</u> (an angle in the triangle is equal to 90°)
Classify by sides = <u>scalene</u> (none of the sides in this triangle is equal)
Answer:
Slope = 0
Step-by-step explanation:
Because there is no change, it's constant, so its equation is y = -1
Answer:

Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
