Yes, so as long as the angle being identified (in this case, angle b) is in the center.
two lines intersect at point b which is also end point of two rays
The vertex of an angle is the point where the two rays meet. An example is angle ABC. the two rays are ray BA and ray BC. The two rays meet at point B.
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
The vertex is b and the rays are ba and bc.
'a' and 'b' must both be acute, complementary angles.
Draw two line segments, AB and BC, meeting at a right angle at the point B. Pick any point, D, in the plane, which is inside angle ABC or its opposite angle. Join CD and AD. Then ABCD will be a quadrangle which meets the requirements.
Angle B is congruent to Angle E.
angle B angle Y
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
A = 18.1 degrees B = 54.3 degrees C = 107.6 degrees
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.
False : Cos B = 16.67/24 = 0.6946 : Therefore angle B = 46° (not 26°).
A = 60 B = 20 C = 140 This can have a large number of answers.
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.
Triangle ABC is congruent to triangle XYZ if AB=XY, BC=YZ, and CA=ZX. Also angle A=angle X, angle B=angle Y, and angle C= angle Z.
B = 3A : C = 0.9 x 6A Therefore 180 = A + B + C = A + 3A + 5.4A = 9.4A : A = 180 ÷ 9.4 = 19.15° (2dp) Then B = 57.45° and C = 103.40°
Statement Reason1. triangle ABC is equilateral..............................................given2. AC is congruent to BC;AB is congruent to AC........................................definition of equilateral3. angle A is congruent to angle B;and B is congruent to angle C.............................Isosceles Theorem4. angle A is congruent to angle C..................Transitive Property of Congruence5. triangle ABC is equiangular...............................Definition of equiangular
B = 5A C = 4A - 8 The sum of the angles of a triangle = 180° A + B + C = 180 A + 5A + (4A - 8) = 180 10A = 188 A = 18.8° (and therefore B = 94° and C = 67.2°)
True : Sin B = 13.5/28.9 = 0.46713 : Therefore Angle B = 27.8 (1dp)
