Is a scalene triangle an isosceles triangle?
yes a scalene triangle is a isosceles triangle.* * * * *No. A scalene triangle is not an isosceles triangle. The sides of a scalene triangle must all be of different lengths. In an isosceles triangle two of the sides must be the same length. If all three sides are different (scalene) then two cannot be the same (isosceles).
What must true statement about a 30 angle and 60 angle triangle?
That it must be a right angle triangle because the 3rd angle must be 90 degrees
Does an equilateral triangle have three congruent sides?
Yes, because "congruent" sides must be of equal length. The 3 sides of an equilateral triangle are all equal. Furthermore the three angles inside the triangle are all equal, so each one is 180 degrees divided by 3 = 60 degrees.
If the sum of the measures of two angles of a triangle is equal to the measure of the third angle the triangle must be?
...a right triangle.
If triangle PQR is congruent to triangle STU which statement must be true?
PQ ST
What type of triangle has its orthocenter outside of the triangle?
The orthocenter of a triangle is found at the intersection of the three altitudes of the triangle. Obtuse triangles contain altitudes which are found outside of the triangle, meaning their orthocenter must be outside of the triangle as well.
The orthocenter of a triangle may lie outside the triangle because the altitude does not necessairly intersect the of the triangle?
The orthocenter of a triangle may lie outside the triangle since the ___altitude___ may not intersect any side of the triangle. * * * * * No. One of the altitudes must intersect the side opposite it and so it is not correct to say ANY side of the triangle.
If the intersection of the perpendicular bisectors of the sides of a triangle lies on one of the sides of the triangle the triangle must be?
A right triangle. See: http://en.wikipedia.org/wiki/Circumscribed_circle#Circumscribed_circles_of_triangles
What is the fewest number of medians that lie within a triangle?
All three medians MUST lie inside the triangle.
How do you draw Euler's Line?
to draw a euler line, you must know how to draw the following terms... orthocenter, circumcenter, and centriod of a triangle, once you have drawn the following points, connect them to make a straight line, if they don't form a straight line, try again, and be as accurate as possible :)
What must all the sides of a triangle added together equal?
There are 3 sides to a triangle and 3 inside angles that add up to 180 degrees The sum of the two shorter sides must be greater than the third side.
Why can some isosceles triangles be ringt angle triangles?
An isosceles triangle only requires that two of its inside angles be equal to eachother. Therefore, a right angle triangle (90 degree inside angle) with two 45 degree inside angles on the the two other corners would be considered an isoceles triangle. However, this would be the ONLY right angle triangle that would be considered an isoceles triangle since all inside angles must add up to 180 (90+45+45=180).
What does a square with a triangle inside mean?
Square represents PI squared divided by 7. The triangle represents the square root of PI times 65. You must find the area of the triangle and square and multiply them. Then find the protocol of all your answers square roots. Then, you must add the answers together. This is what it means.
What type angles does an isosceles triangle have?
All you can say about the angles inside every isosceles triangle is: -- Two of them are equal, and they must be acute (less than 90°). -- The third angle must be less than 180° . -- Just as in any other triangle, all three angles add up to 180° .
How much information do you need to make a triangle?
It must have 3 sides and 3 inside angles that add up to 180 degrees
Is an arch a triangle?
A triangle must have straight lines.
What triangle has 8 sides?
There is no such triangle. A triangle must have exactly 3 sides.
