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
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.
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.
You draw an angle and its vertex should be A on its left B and on its right C. ( An Acute)Confirmed
Angle C is an acute 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
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
C

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.
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.
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.
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.
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).
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.
