Which of the following is not an appropriate method of proving triangles congruent a) aaa b)sss c) aas d) sas

a) AAA.

Step-by-step explanation:

Triangles which are of the same shape and size are called congruent triangles. Triangles of same shape are similar triangles.

Two triangles can be proved congruent by SSS ,SAS AAS ,ASA ,HL  postulates.

Two triangles can be proved similar by AAA method.

All congruent triangles are similar but all similar triangles are not congruent.

Hence option a) AAA is not an appropriate method of proving triangles congruent.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
