Algenib and Algol form with γ Andromedæ, a right-angled triangle.
The glass shows two small stars forming a right-angled triangle with it.
Pythagoras is related to have been the first who saw, in the clear light of demonstration, the property of the right-angled triangle, of which we have spoken.
In a right-angled triangle, the square of the number which expresses the length of the hypothenuse is equal to the sum of the squares of the numbers which express the lengths of the other two sides.
The square constructed on the hypothenuse of a right-angled triangle is equivalent to the sum of the squares constructed on the other two sides.
The squares constructed on the two sides of the right angle of a right-angled triangle and on the hypothenuse are to each other as the adjacent segments and entire hypothenuse.
It is this: "In every right-angled triangle, the sum of the squares of the base and perpendicular is equal to the square of the hypothenuse.
Algenib in Perseus and Almaach and Algol in Andromeda form a right-angled triangle, illustrate the 47th problem, and display the Grand Master's square upon the skies.
Also AEC is a right-angled triangle, and the square of 5 added to the square of 7 equals 74, the square estate on A C.
Defn: The side of a right-angled triangle that is opposite to the right angle.
Defn: Having an obtuse angle; as, an obtuse-angled triangle.
We reply to you, and we show to you that we can reason by indicating that the square of the hypothenuse of a right-angled triangle is equivalent to the sum of the squares of the other two sides.
There was the right-angled triangle, its lines reproduced in unbroken brilliancy, and there were the added lines used in the familiar demonstration, broken at intervals to indicate their use.
An important application of these theorems is at once made to a right-angled triangle, viz.
In a right-angled triangle, if a perpendicular be drawn from the right angle to the base, the triangles on each side of it are similar to the whole triangle, and to one another.
Thus, according to his plan, we should have a right-angled triangle, with the right angle next to the frontiers of Carmania, and its hypotenuse less than one of the sides about the right angle!
The side of a right-angled triangle that is opposite to the right angle.
It contains the lengths of the two sides of a right-angled triangle, usually for every quarter of a degree of angle, and for lengths of the hypothenuse, from 1 to 100.
Thus Euclid defines an acute-angled triangle as one which has three acute angles.
He might have said that an acute-angled triangle is one which has neither a right angle nor an obtuse angle: but rightly preferred to throw the same statement into a positive form.
An acute-angled triangle is one which has an acute angle.
Various writers have discussed the properties of the right-angled triangle, but we all know that a square erected on a hypothenuse of a right-angled triangle is equal to the sum of the squares erected on the base and perpendicular.
These represent the run of the brace, or the length of two sides of a right-angled triangle; the figures immediately to the right represent the length of the brace or the hypothenuse.
The length of any brace simply represents the hypothenuse of a right-angled triangle.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "angled triangle" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
