The sum of the 3 interior angles of any triangle ... no matter how large or small ... is always 180 degrees. This rule has no connection to the perimeter of the triangle. The perimeter may be one inch, less than one inch, 10 miles, more than 1,000 miles, etc., and the sum of the interior angles is always the same 180 degrees.

90 degrees. This is an isosceles right triangle, standing on its hypotenuse.

Any value between 0 and 360 degrees excluding 180 degrees and the two extreme values. The exception is a triangle where it cannot be as large as 180 degrees.For a regular convex polygon, each interior angle is determined by the number of sides n:interior angle = 180 (n-2) / nFor an equilateral triangle, 180 x (1) / 3 = 60For a square 180 x (2) / 4 = 90 (right angles)

Let x equal the first angle.let 4x= the second anglelet 3x+10x+4x+3x+10=180 The sum of the interior angle measures of a triangle is 180 degrees.8x+10=180 combine like terms8x=170 addition(subtraction) property of equalityx=21.25 degrees

No but the sum of the squared sides will equal the square of the hypotenuse using Pythagoras' theorem for a right angle triangle

The angles could work out as: 1st angle = 90 degrees, 2nd angle = 30 degrees and 3rd angle = 60 degrees because the 3 angles add up to 180 degrees

the ratios in such a triangle are 1:2:sqrt(3) so the longest length is opposite the 90 degree angle and is twice as large as the length opposite the 30 degree angle

A = 60 B = 20 C = 140 This can have a large number of answers.

60 degrees.

The first angle that is half as large as the other angle is 30º The other angle that is the larger is 60º

First angle=X Second angle=4x Third angle=5X-45 Since the angles of a triangle always = 180o x+(4X)+(5X-45)=180o 10X-45=180 10X=225 X=22.5 Therefore. . . First Angle=X=22.5o Second Angle=4X=90o Third Angle=5X-45=67.5o

Yes 2 congruent right angle isosceles triangles joined together will make a square
