True or false Dilating a triangle changes the angles and side length of the triangle?
False.
Triangle with sides of lengths 20 21 and 29 is a right triangle true or false?
TRUE
AAA angle angle angle guarantees congruence between two triangles?
true apex :)
True or false A triangle with sides of lengths 10 24 and 27 is a right triangle?
false In order for this to be a right triangle, the sum of the squares of the two shorter sides would have to equal the square of the longest side. 102=100 242= 576 272=729 102+242= 676, which does not equal 272=729, so a triangle with these lengths is not a right triangle.
True or false Two right triangles that are not similar still may have one congruent acute angle in common?
False. Assume that you had a two right triangles with one congruent acute (<90 degrees) angle in common. Let x represent the number of degrees in this angle in both triangles (which we can do since the angles are congruent). Let y represent the degree of the other angle in the first triangle and let z represent the degree of the other angle in the second triangle. We know that the sum of the degrees of the angles in a triangle is 180. So for the first triangle we have, 90+x+y = 180 For the second triangle, 90+x+z=180 Therefore, 90+x+y=90+x+z Subtract the 90+x from each side: y=z Therefore the degrees of the angles of the two triangles both are 90 [because they are both right triangles], x [because we said that this is the number of degrees of the congruent angles given in the problem], and y [because y=z]. Because the three angles of both triangles have the same measurement, the triangles must be similar.
Can a triangle have both an acute an a right angle true or false?
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
Is it true or false that an isosceles triangle may have a right angle?
It is true.
Is it true or false that the legs are the sides that form the right angle in a right triangle?
It is true and the longest side of a right angle triangle is its hypotenuse.
True or false Every point on a median in a triangle is equidistant from the sides of a angle?
False
Is this True or false the angle bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the base?
True
A triangle cannot have more than one right angle true or false?
True
True or false does a triangle cannot have more than one obtuse angle?
True
Is this statement true or falseThe circumcenter of a triangle is the point of concurrency of the angle bisectors of a triangle?
false
In a scalene triangle the longest side is opposite the angle with smallest measure true or false?
False
True or false in a scalene triangle the longest side is opposite the angle with the smallest measure?
False
In a scalene triangle the longest side is opposite the angle with the largest measure true or false?
True
Is it true or false that a right triangle can be scalene?
A right angle triangle can be scalene. Such a triangle has one right angle, two other unequal angles and no equal sides
