What kind of triangle always has 3 acute angles and 3 sides the same length?
Equilateral triangles have 3 sides of equal length, and 3 angles with measures of 60 degrees each.
How many possible triangles can be formed if angle J is acute and the length of side j is equal to the height of the triangle?
Infinitely many.
What are 10 properties of a rectangle?
1. Opposite sides are equal 2. it is a parallelogram 3. all 4 angles (at vertices) are 900 4. diagonals are equal in length 5. diagonals bisect each other 6. triangles formed by a diagonal and 2 sides (opposite side for each triangle) are congruent 7. among the four triangles that are formed by the 2 diagonals, the vertically opposite triangles are congruent 8. if length=breadth, then the rectangle is a square 9. perimeter of the rectangle = 2 * ( length + breadth) 10. area of rectangle = length * breadth
What does length measure?
it measures length.
What is the perimeter of an equilateral triangle that measures 15 feet on one side?
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
Congruent triangles have the same shape and size because they will always have the same?
Congruent Triangles have the same angles and side length measures
What triangles are formed when you draw a line down the middle of an equilateral triangle?
an icoceles triangle or a scalene triangle Actually you would get two right angled triangles. Isosceles triangles have two sides which are equal in length. A scalene triangle has all sides a different length and no right angles.

How do you find the measures of a right angle with length and width shown?
A right angle is always 90 degrees. Another Answer:- If you mean the length of the hypotenuse then use Pythagoras' theorem which is applicable to right angle triangles

Can any two triangles be joined to make a rhombus?
No. A rhombus has all four sides of equal length. To split a rhombus into only 2 triangles, it must be split along a diagonal; which means that 2 of the sides of one of the triangles must be the same length as the sides of the rhombus, which being equal mean the triangles must be (at least) isosceles - scalene triangles will not work. Further, as the diagonal will be a common length to each of the triangles (the length of their third sides), it will form the base (ie the side opposite the vertex between the sides of equal length) of the isosceles triangles, and so the triangles must be to congruent isosceles triangles. If the diagonal has the same length as the side of the rhombus, then the two congruent triangles will be congruent equilateral triangles.

When are two isosceles triangles congruent?
the triangles will have the same side length

it measures length.
What is the surface area of a triangular prism with 6 6 5 and 9?
Assuming the four numbers given are measures (in some unknown units) of the three sides of the triangles and the length of the prism, it is impossible to answer the question without knowing which one of them is the length.
