Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x
The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question.
In terms of algebra, the rule is
x+y = z
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

Answer:
A triangular scarf is an isosceles right triangle.
Step-by-step explanation:
Given: A scarf is a triangle with two perpendicular sides that are the same length.
We have to name which two terms describe a triangular scarf.
Isosceles triangle is a triangle with length of two of its sides equal.
Right angled triangle is a triangle in which one angle is a right angle.
Given :
The two sides of scarf are perpendicular to each other.
Thus, the angle formed between them is 90°. Hence, right angled triangle.
Also, length of two sides are same, Hence isosceles triangle.
Thus,a triangular scarf is an isosceles right triangle.
