What does the law of cosines reduce to when dealing with a right triangle?
D. The Pythagorean Theorem
What theorem or postulate can be used to justify that the two triangles are congruent?
Pythagorean theorem
What kind of triangles does the Pythagorean theorem work for?
All right angle triangles
Does the Pythagorean Theorem work on all triangles?
No, the pythagorean theorem only works on right triangles, but it will work on any right triangle. This is because the Pythagorean Theorem states that length of Leg A squared plus the length of Leg B Squared equals the length of the hypotenuse squared. A hypotenuse is always found opposite a right angle. Only right triangles have right angles; therefore, the Pythagorean Theorem only applies to right triangles. :D
How is the Pythagorean Theorem and Distance Formula the same?
Because they both involve right angle triangles
What happens to the formula for the Law of Cosines when C A or B is 90 degrees?
It simply reduces to the pythagorean theorem
What is a theme for a math project?
You could use the Pythagorean Theorem and many triangles You could use the Pythagorean Theorem and many triangles
What triangles does Pythagoras theorem include?
The Pythagorean theorem only includes right triangles
How do you find the perimeter of a parallelogram using Pythagorean theorem?
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
What does the law of cosines reduce to when dealing with a right triangle?
D. The Pythagorean Theorem
Is the pythagorean theorem true for an acute triangle?
No, the Pythagorean Theorem only works on right triangles. You could use the law of cosines, though: c^2=a^2+b^2-2ab*cos(C) Where C is the measure of the angle between sides a and b.
Does Pythagorean Theorem apply to triangles?
Yes. But only right triangles.
What kind of triangles relate to Pythagorean theorem?
Right-Angle triangles
What are the types of triangles that can use the Pythagorean theorem?
Right angle triangles
Is it true that Pythagorean theorem can only be used for right-angled triangles?
Yes. The Pythagorean Theorem is true for only right triangles. However, a variety of other similar equations can be used for other triangle types. Law of Sines: a/sinA = b/sinB = c/sinC Law of Cosines: c2 = a2 + b2 - 2ab*cosC
What does the pythagorean theorem apply to?
right angled triangles
When does the Pythagorean theorem apply?
With right angle triangles
