How do u solve number 11

#11 is an isosceles triangle which means 2 sides are the same. If they give you the hypotenuse, then I'm assuming the 2 same sides are unknown.

Using the Pythagorean Theorem, a^2+b^2=c^2, then you get:

a²+b²=8²

a²+b²=64

Which means a² and b² must be 32 each because they are the same. Find the sqrt of 32 for the smaller legs.

1) is right

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
