Can a triangle have a straight angle in it?
no
What shape has one right angle and three straight sides?
a right triangle
What if a triangle has one angle equal to 180 degrees?
It would be a straight line.
Can these legs form a right angle 200 200 and 400?
As a triangle - no. Only a straight line.
A triangle with an angle whose measures is greater than 90?
180 > x > 90: obtuse 180: straight 360 > x > 180: reflex
Can a triangle have a straight angle in it?
no
Can the exterior angle of triangle be straight angle?
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
What is the angle bisector of a triangle?
It is a straight line which divides an interior angle of the triangle into two angles of equal measure.
Can a equliteral triangle be a acute angle?
No, an angle is not a polygon - lie a triangle - which is a closed plane shape bounded by straight lines.
How is constructing a perpendicular bisector different to constructing an angle bisector?
A perpendicular bisector is a straight line that divides a side of a triangle in two and is at right angles to that side. An angle bisector is a straight line that divides an angle of a triangle in two.
What is a real life example of an acute angle?
A right angle triangle always has 2 acute angles within it.
What is a striaght triangle?
Probably a right angle triangle because it has 2 straight sides that are perpendicular to each other
When you trisect a right angle you first construct what kind of triangle?
To trisect a right angle form an equilateral triangle with one vertex at the right angle and then bisect that angle of the equilateral triangle. (It is impossible to trisect a general angle using only compass and straight edge - the right angle is a specific exception.)
What 2d shape has 1 right angle and 3 sides are straight?
triangle
What if a triangle has one angle equal to 180 degrees?
It would be a straight line.
What shape has one right angle and three straight sides?
a right triangle
Can a triangle have a straight angle?
If you mean by straight angel an angel of magnitude 180 degrees, then the answer is no. The sum of the three interior triangle angels is 180 and not only a single angel.
