Depends on your entry way design. I think your door should open to the smallest side of the entry, e.g. against the wall and away from the coat rack or bench or whatever. I've seen them open both left and right sides. I think I prefer a left opener (personal preference). But, why do most exterior doors open inward? I think it's a waste of space....
Consider a right triangle. One of the exterior angles 90 degrees.
that is a big NO kids should be healthy, active, and eating right
900
3 right angles
When this happens, it means the exterior light has burned out - the light on the inside is blinking faster as a warning. I've been through this several times. Replace the exterior bulb and the blinker should return to normal.
No.
If exterior angle makes linear pair with the right angle then exterior angle is 90o.If exterior angle makes linear pair with any of the other two angles then it is greater than 90o i.e. obtuse angle.Consider a right triangle ABC, right angled at B.We have: ∠B = 90o and ∠A + ∠C = 90o.Let us consider exterior angle be x.If exterior angle is supplement to B(i.e. ∠B + x = 180o or linear pair) then exterior angle(x) = ∠A + ∠C = 90o.If exterior angle is supplement to any of the other two angles then exterior angle is greater than 90o.Let us say x is supplement to ∠A then x = ∠B + ∠C = 90o + ∠C.And 90o + ∠C is greater than 90o so, x is obtuse angle.
A right angle is not 125
No
To determine if an exterior door is left-handed or right-handed, stand outside the door and observe which side the hinges are on. If the hinges are on the left, it is a left-handed door. If the hinges are on the right, it is a right-handed door.
No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.
135 degrees.
