The ph level of a solution measures how acidic or basic the solution is. values between 0   and 7   are considered acidic while values between 7   and 14   are considered basic. the ph is calculated by using the equation ph =−log⁡⁡[h3o+] . the notation ­ ­ ­ [h3o­­­+]   represents the concentration of hydronium ions, which is measured in units of moles per liter, m .    what is the ph level of a solution if [h3o+]=3.4×10−3m ?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
