How do you name a right angle?
You use the points of the vertex and on the two sides. For example a right angle with a vertex of A and two sides B and C. would be Angle BAC
How many ways to name an angle?
There are three ways to name an angle, provided there are only three points on the angle. Say the vertex is point A, and there are two rays extending. Each has another point on it, points B and C. You can name this angle BAC, CAB, or A.
Vertex angle A of isosceles triangle ABC measures 20 degrees more than three times measure of angle B Find angle C?
The vertex angle of an isosceles triangle is the angle opposite the base of the triangle. Therefore, the other two remaining angles of the triangle are congruent. so, in this problem: Let x = m of angle B Let x1 = m of angle C Let 3x + 20 = m of angle A x + x + 3x + 20 = 180 5x + 20 = 180 5x = 160 x = 32 degrees Since angle B and C are congruent, the measure of angle C = 32 degrees.
How do you draw line AB and Line AC in Geometry?
You draw an angle and its vertex should be A on its left B and on its right C. ( An Acute)Confirmed
The measure of angle C is 51 degrees Classify angle c?
Angle C is an acute angle.
How do you name a right angle?

What are the ways to name an angle?
The VERTEX of the angle is always in the middle... so if it is angle ABC, then you can also name it CBA as long as the vertex letter is in the middle, usually there are only 2 ways to name an angle.Also, if there aren't any other angles with the same vertex, you can just call angle ABC, angle B.Summary: If you have an angle:the vertex is labeled B, the others are A and C. what can you call the angle?Answer: ABC,CBA or B
What is the vertex of angle bcd?
C
In which region of angle CAB does point C lie?
vertex

What does it mean by name an angle three ways?
For example, you might name an angle as "ABC", where "B" is the vertex, and "A" and "C" are points lying on the sides of the angle. If there are additional points on the same sides, you can substitute those points instead.
In which region of angle CAB does point B lie?
the letter C lies on top, the first point of the angle. A is the "vertex" it connects both lines to form an angle the bottom could be letter B. "<" that's an angle. B and C could never be on the Vertex.
What are three ways to name an angle?
Acute: 0 < X < 90; Right: = 90; Obtuse: 90 < X < 180; Straight: = 180; Reflex: 180 < X < 360. The Acut, Right, Straight and Reflex are actually classifications of an angle. Naming of an angle is done by identifying the vertex and a combination of the vertex and points on the two rays. For example an angle with points ABC where B is the vertex and A and C are points on the accompanying rays may be named as angle B, angle ABC or angle CBA. These can be written with the symbol for angle placed before the B the ABC and the CBA.
What is the vertex angle of an isosceles triangle whose equal sides are 15 meters long if the area is 112.5 square meters?
Area = 0.5*a*b*sin(C) so 112.5 = 0.5*15*15*sin(c) 1 = sin(C) so C = pi/2 radians (or 90 degrees).
Vertex angle A of isosceles triangle ABC measures 20 degrees more than three times measure of angle B Find angle C?
The vertex angle of an isosceles triangle is the angle opposite the base of the triangle. Therefore, the other two remaining angles of the triangle are congruent. so, in this problem: Let x = m of angle B Let x1 = m of angle C Let 3x + 20 = m of angle A x + x + 3x + 20 = 180 5x + 20 = 180 5x = 160 x = 32 degrees Since angle B and C are congruent, the measure of angle C = 32 degrees.
What is a c angle proper name?
Supplementary angle
How do you draw line AB and Line AC in Geometry?
