Help me to do b no question ​

Step-by-step explanation:

a. Acute angle

b. obtuse angle

c. reflex angle

d. obtuse angle

e. obtuse angle

f. right angle

g. acute angle

h. acute angle

i. reflex angle

j. obtuse angle

hope it helps.

Step-by-step explanation:

b. is a obtuse angle.

For reference use the following:

Classifying angles

acute angle (0<x<90)

right angle (90)

obtuse angle (90<x<180)

straight angle (180)

reflex angle (180<x<360)

Use a protractor to help you find the angles.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
