What’s a Midsegment of triangles?
A Midsegment of triangles is a segment that connects the midpoint of two sides of a triangle.
What are the six types of triangles?
Scalene triangle
Acute triangle

What are the rules for adding and subtracting polynomials?
You add polynomials when there are plus signs. You subtract them when there is a minus sign. Remember to only add/subtract like terms within the polynomials.
How do you find area in algebra?
To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.
What’s a Midsegment formula?
DE=12BC
What do you call a polygon with 7 sides?
A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… The names of polygons are derived from the prefixes of ancient Greek numbers.
What are the steps in adding polynomials?
Step 1: Arrange each polynomial with the term with the highest degree first then in decreasing order of degree. Step 2: Group the like terms. Like terms are terms whose variables and exponents are the same. Step 3: Simplify by combining like terms.
What is perimeter and area?
About Transcript. Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
How do you find the midsection of a triangle?
Is one-half the length of a third side (base) and also parallel to the base.
What is a 100 sided shape?
A hectogon or hecatontagon or 100-gon is a hundred-sided polygon
What is the rule for adding and subtracting Monomials?
To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same. on the variables the same.
How do you solve for perimeter?
To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
What theorem can be used to find a missing length in a right triangle?
The Pythagorean Theorem can be used to find the value of a missing side length in a right triangle.
Do isosceles triangles have the same angles
An isosceles triangle therefore has both two equal sides and two equal angles. ... The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.
How do you multiply polynomials with different exponents?
Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents. Step 2: Combine like terms (if you can). Step 1: Distribute each term of the first polynomial to every term of the second polynomial.
Is y 6 a polynomial?
A polynomial may have more than one variable. For example, x + y and x2 + 5y + 6 are still polynomials although they have two different variables x and y. By the same token, a monomial can have more than one variable. ... A monomial will never have an addition or a subtraction sign.
How do you find the missing length?
The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a2.
How do I find the height of an isosceles triangle?
We can find the height by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them. We now know the height of the triangle and can use this to go back and find the area of the isosceles triangle.
What is the difference between adding polynomials and multiplying polynomials?
To add or subtract polynomials, line up the coefficients with like terms and then add or subtract them. ... To multiply two polynomials, each term of the first polynomial must be multiplied by each term of the second polynomial.
