Can a right triangle be acute or scalene or isosceles?
A right triangle may be isosceles or scalene (though not at the same time), but never acute, since an acute triangle is defined as having all interior angles less than 90°. A right triangle by definition has one 90° angle.
Is an isosceles triangle always congruent to a right triangle?
Not all the time but it can happen
Is an isosceles triangle an example of an acute angle?
For starters, here are the basic rules of triangles.A right angle is 90 degrees.An acute angle is less than 90 degrees.An obtuse angle is more than 90 degrees.A triangle's angles always add up to 180 degrees.An isosceles triangle has two sides that are the exact same length and thus two same angles.Now, an isosceles triangle can have all acute angles. For example, its angles can measure in degrees at 80, 50, and 50. However, isosceles triangles can also have an obtuseangle.For example, consider a triangle with the following angle degree measures: 96, 42, 42.With the rules above in mind, the triangle above is an isosceles triangle because two angles are the same and they both are acute. At the same time, the remaining angle is greater than 90 degrees and so is obtuse. Thus, a single triangle can have both acute and obtuse angles.Similarly, you can have a right triangle that is also isosceles, with the angle degree measurements at 90, 45, and 45.
How much rotational symmetry does triangle have?
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
Does an isosceles triangle have two pairs of parallel sides?
Well, honey, an isosceles triangle has two sides that are equal in length, but that doesn't mean they're parallel. In fact, the only time an isosceles triangle would have two pairs of parallel sides is if it magically transformed into a parallelogram overnight. So, no, an isosceles triangle does not have two pairs of parallel sides.
What is a polygon with three sides of different lengths?
Oh honey, that's what we call a scalene triangle. It's like the quirky cousin of the triangle family - all sides are different lengths, making it stand out from the crowd. So next time you see a triangle with sides that can't agree on a length, you'll know it's a scalene triangle strutting its stuff.
What is a triangle with only 2 congruent sides?
Well, honey, that's what we call an isosceles triangle. It's like having a fancy cocktail with two matching umbrellas - a little bit special, but not too over the top. So, next time you see a triangle with two equal sides, just remember it's called an isosceles triangle and impress your friends with your newfound geometry knowledge.
How would you construct an isosceles triangle if only given the vertex angle and the radius of the circumscribed circle?
You have an isosceles triangle, and a circle that is drawn around it. You know the vertex angle of the isosceles triangle, and you know the radius of the circle. If you use a compass and draw the circle according to its radius, you can begin your construction. First, draw a bisecting cord vertically down the middle. This bisects the circle, and it will also bisect your isosceles triangle. At the top of this cord will be the vertex of your isosceles triangle. Now is the time to work with the angle of the vertex. Take the given angle and divide it in two. Then take that resulting angle and, using your protractor, mark the angle from the point at the top of the cord you drew. Then draw in a line segment from the "vertex point" and extend it until it intersects the circle. This new cord represents one side of the isosceles triangle you wished to construct. Repeat the process on the other side of the vertical line you bisected the circle with. Lastly, draw in a line segment between the points where the two sides of your triangle intersect the circle, and that will be the base of your isosceles triangle.
What shape has no lines of symmetry and rotational symmetry order 4?
The shape that has no lines of symmetry and rotational symmetry order 4 is a scalene triangle. A scalene triangle is a triangle with three unequal sides and three unequal angles. It does not have any lines of symmetry because its sides and angles are not equal, and it has rotational symmetry of order 4 because it looks the same after being rotated by 90, 180, or 270 degrees.
Does the angle bisector in a triangle bisect the opposite side?
Not necessarily. The only time that the angle bisector would bisect the opposite side is if you were bisecting the vertex angle of an isosceles triangle.
Do all sides of a triangle have to be the same length?
No. The only time they have to be the same length is in an equilateral triangle.
