If it's a 45, 45, 90 triangle, then both legs must be equal in length.

umm??????

On a piece of paper, use a protractor to construct △ABC with m∠A=30° , m∠B=60° , and m∠C=90° . Which statements about the triangles are true? Select each correct answer. BC<AC BC>AC BC>AB BC<AB
Shadow:
The sum of all angles in a triangle is 180. 90 + 45 + 45 = 180 If the side across the from an angle of 45 is 4, then the side across from the other 45 angle is also 4. AC = 4

Shadow:
Sizes are not scaled. But based on what you learned in the previous problem, do you think the side across from angle A (30) is larger or smaller than the side across from angle B (60)
Shadow:
If you are confused, please let me know

dude:
That should help
22west:
no idea what that is representing
dude:
That represents the side measures of a 30-60-90 degree triangle
22west:
ok
22west:
dont walk me throught it or anything
dude:
|dw:1518129767652:dw|
22west:
yeah right
dude:
Just compare the side measures based on the answer choices For example line CB is x Line AB is 2x
22west:
Dude, my teachers didn't walk me through this. That is why i'm depending on you to help me. But when you just put that up it confuses me.
dude:
Did you learn the 30-60-90 right triangle theorem?
22west:
No. My teachers walked me through none of this.
22west:
This just looks like shapes, letters, and numbers to me.
22west:
Not without permission but i'll tell my mom and step-dad that it's school.
dude:
Ah okay
dude:
It is a short clip talking about 30-60-90 degree right triangles and their rules
22west:
I don't understand at all.
dude:
Welp I am taking this another step back Do you know what the angle measures inside a triangle should equal?
22west:
180°
