Two triangles are similar. Find the values of x and y when the height is 6.5 and base is x on the first triangle second triangle the height is 26 and base is y. area is 7.8 and could belong to either?

Their values are: x = 2.4 and y = 0.6 which is a ratio of 4 to 1 and both triangles have an area of 7.8 square units

Are angles in an isoceles triangle equal?
Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.
What kind of triangles are there?
There are many kind of triangles. These are the following: Acute, Right, and Obtuse are actual angles. Scalene, Isosceles, and Equilateral are all actual triangles. But, you can have any triangle with any angle. Like a scalene triangle with a Right angle, or an Isosceles triangle with an Obtuse angle.Acute is a triangle with an angle less than 90 degrees. So it is smaller than a Right triangle. To make and Acute triangle, you need at least two Acute angles.Right triangle have at least on right angle. Right angles are angles that re exactly 90 degrees. If you put a cube right where the angle went, both sides would be perfectly straight.Obtuse triangles are triangles with at least one Obtuse angles. They are always bigger than 90 degrees. They are larger than a Right triangle. If you spread your legs apart, you would have an Obtuse angle.Scalene triangles are triangles with all of the sides different lengths. Each side is either longer or shorter, they are never the same.Isosceles triangles are triangles with two sides the same lengths. The other side is either longer or shorter.Equilateral triangles are triangles with ever side the same exact length. They all are exactly the same. If one is different, it's not an Equilateral triangle.
How are the triangles the same?
-- both triangles lie flat -- both triangles have three sides -- both triangles have three vertices (vertexes, points) -- both triangles have three inside angles and three outside angles -- neither triangle has more than one obtuse angle or more than one right angle inside it -- neither triangle has less than two acute angles inside it -- the inside angles of each triangle add up to 180 degrees -- the outside angles of each triangle add up to 360 degrees -- neither triangle has any side parallel to any other side -- the area of each triangle is half of the product of its base and its height -- no side of either triangle is longer than the sum of its other two sides -- no side of either triangle is shorter than the difference of its other two sides
What is the base of the triangular prism?
well there are three rectangles and 2 triangles so it could be either a rectangle or a triangle!!!! Helen Prism is a body, formed by extruding a given area in a plane perpendiclar to that plan which consists the give area. In case of triangular prism, triangle is stretched to form a volume. It includes two triangles with threee rectangles. Either of triangle can be treated as base of the prism.
Can a right triangle be isosceles or scalene?
Yes, it can be either of those.A couple of right triangles:-- 3, 4, 5 . . . . . scalene-- 1, 1, sqrt(2) . . . . . isoscelesA right triangle can NOT be equilateral.
Are angles in an isoceles triangle equal?
Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.
How many do all triangles measure?
I'm pretty sure all triangles measure 180 degrees because they have three angles that are either acute, right, or obtuse angles and the triangle has to be either an equilateral, iscoceles, or scalene triangle.
Does a right triangle have two sides that are the same length?
In can, but it doesn't have to. Triangles can be either isosceles or scalene.

What are the different kind of triangles?
there is the Equilateral Triangle which all sides are equal.there is the Isosceles Triangle where only two sides are equal.there is the Scalene Triangle where no sides are equal.can help you:http://www.easycalculation.com/trigonometry/triangles-sides.php

How do you prove triangles similar?
To prove that two or more triangles are similar, you must know either SSS, SAS, AAA or ASA. That is, Side-Side-Side, Side-Angle-Side, Angle-Angle-Angle or Angle-Side-Angle. If the sides are proportionate and the angles are equal in any of these four patterns, then the triangles are similar.
Does an equilateral triangle have line symmetry?
In order to have any lines of symmetry, a triangle must have either two sides equal (isosceles) or three sides equal (equilateral).
Can a right triangle be isosceles or scalene?
Yes, it can be either of those.A couple of right triangles:-- 3, 4, 5 . . . . . scalene-- 1, 1, sqrt(2) . . . . . isoscelesA right triangle can NOT be equilateral.
How do you prove that two triangles are similar?
You either show that the corresponding angles are equal or that the lengths of corresponding sides are in the same ratio.
What is a polar triangle in spherical trigonometry?
A polar triangle in spherical trigonometry is a triangle that has one vertex at either of the Earth's poles. Spherical trigonometry deals with measuring angles and sides in triangles on the surface of a sphere, rather than in a flat plane. Polar triangles can be used to determine the distance between two points on the Earth's surface when the latitudes and longitudes of those points are known.
