Are all regular polygons congruent?

A polygon can have a certain number of sides, but the sides do not necessarily have to be the same length. In the second pentagon, the angles have different measures and the sides have different lengths. A regular polygon has congruent angles and congruent sides. Any polygon can be a regular polygon.

What polygons are congruent?

Two polygons are congruent if they are the same size and shape – that is, if their corresponding angles and sides are equal. Move your mouse cursor over the parts of each figure on the left to see the corresponding parts of the congruent figure on the right.

Are all regular polygons with the same numbers of sides congruent?

Regular polygons are congruent if they have the same number of sides, and: Their sides are congruent, or: Their radii are congruent.

What type of triangle is 9/12 15?

right triangle

What kind of triangle is 9/12 13?

There are infinitely many pythagorean triples. There are 50 with a hypotenuse less than 100 alone. Here are the first few: 3:4:5 , 6:8:10 , 5:12:13 , 9:12:15 , 8:15:17 etc… If you multiply each side by an integer, the result will be another triple, demonstrating that there is an infinite number of them.

What are the angles of a 7 24 25 Triangle?

  • Hence it’s a right triangle with ˆC=π2=90∘
  • ˆA=sin−1(725)=0.2838cor16.26∘
  • ∴ˆB=π−π2−0.2838=1.287cor=73.74∘
  • ˆB=sin−1(2425)=1.287cor=73.74∘

Does 7 10 12 make a right triangle?

The triangle that has side lengths of 7, 10, and 12 is not a right triangle. The correct answer is B.

What type of triangle is 8/10 15?

If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc.

Will it make a right triangle?

If you have the length of each side, apply the Pythagorean theorem to the triangle. If you get a true statement when you simplify, then you do indeed have a right triangle! If you get a false statement, then you can be sure that your triangle is not a right triangle.
