First you would square the length of each of the sides. You'd add the squares of the smaller two numbers. If they are smaller than the square of the biggest side, then the triangle is obtuse. If their sum is bigger, then the triangle is acute. If they are equal, then the triangle is a right triangle.
Example:
length of sides-23, 34, 49
232+342__492
529+1156__2401
1685<2401

What is the length of the longest side the perimeter of the triangle is 63 in.?
The perimeter doesn't tell you the length of any of the sides. There are an infinite number of different triangles that all have the same perimeter. The only thing you can tell from a 63-in perimeter is that no side can be 31.5 inches or more.
What is the area of a triangle with a bottom length of 3 yd?
Need to know the triangle's height to tell.
How can you tell whether two polygons are similar?
Polygons will be similar if they have the same number of sides AND all of their angles are the same. All of their angles are the same if all but one of their angles are the same because with the same number of sides the angles must add up to the same thing. All squares are similar (4 right angles and sides of equal lenght). All rectangles are similar (4 right angles). We know two triangle are similar if two or mare angles are the same, or if one angle is the same and the two adjacent sides are the same length. Variations of this last proof may apply to some other polygons.
What else would need to be congruent to show that triangle ABC is congruent to triangle XYZ by Angle Side Angle?
Without seeing the picture, I can't tell what's already known to be congruent, so there's no way I can figure out what 'else' is needed.
How can you tell if two polygons are similar?
The angles are the same, but the sides don't have to be the same length. or Two polygons are similar if and only ifthe corresponding angles are congruentThe corresponding sides must be in a consistent ratio -- for example, if side AB = (2xA'B'), then sides B'C', C'D' ... K'A' must also be twice as long as their corresponding sides BC, CD, ... KA.
What are the names of the triangles and how can you tell?
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.
How can you tell from a obtuse to acute?
an obtuse angle is wider than an acute angle...(:
How do you tell if 2 sides and an angle make a non-right triangle?
If it has an obtuse angle
How do you tell if an angle is acute obtuse or right?
Acute: less than 90o Obtuse: more than 90o Right: exactly 90o
What does the measure in degrees tell you an angles?
It tells you if the angle is acute, right, obtuse or reflex.
What lines are lines that form acute or obtuse angles?
Straight lines! if i didn't answer correctly tell me!
How can you tell the difference between a rectangle and a rhombus?
A rectangle has parallel sides and the 4 corners are 90 degrees each and the length and width will not be the same.A rhombus has parallel sides, all of which are of the same length and the opposite corner pairs are respectively acute and obtuse (a diamond shape with sides of the same length).
How can you tell if a triangle is a right angle?
If it has a 90 degree angle and two acute angles then it is a right angle triangle.
How can one tell what a scalene triangle looks like?
One can tell what a scalene triangle looks like by looking at each side of the triangle. A scalene triangle normally has very different length in each of its sides. It has no equal sides, and no equal angles.
How can you tell if the given lengths can be the sides of a triangle?
you can fine the perimeter
Examples of analogy reasoning in geometry?
One example of analogy reasoning in geometry is when you have to figure out what type of triangle a triangle is. For example, if you have a triangle with three sides and you can tell the sides are the same size, you can deduce you have an equilateral triangle, even without measuring it.
How can you tell if its a real triangle?
When it has 3 sides and 3 angles that add up to 180 degrees
