Answer:</h2>
∠LMN is a right angle
<h2>
Step-by-step explanation:</h2>
If we want to prove that two right triangles are congruent by knowing that the corresponding hypotenuses and one leg are congruent, we begin as follows:
- Since two legs are congruent and we know this by the hash marks, then the triangle ΔLKN is isosceles.
- By definition LN ≅ NK
- If ∠LMN is a right angle, then MN is the altitude of triangle ΔLKN
- Also MN is the bisector of LK, so KM ≅ ML
- So we have two right triangles ΔLMN and ΔKM having the same lengths of corresponding sides
- In conclusion, ΔLMN ≅ ΔKMN
1st you combine like terms so subtract 7y and 3y and you get 4y. So this is the final answer: 4y+4b.
Answer:
Step-by-step explanation:
Acute : An acute triangle is one in which all the angles less than 90 degree.
Right: Any triangle whose one angle measure is 90 degrees is called Right angled triangle.
Obtuse angle: Any triangle whose one angle measures more than 90 degrees is called Obtuse angled triangle.
Equilateral : Any triangle whose all the sides are equal are called equilateral triangle. They also have all the angle equal which measures 60 degrees.
Scalene triangle : The triangle whose length of all the sides are different from each other are called scalene triangle.
Isosceles : the triangle whose two sides length are equal are called Isosceles triangle.
